Automatic Transmissions Problems need Diagnosis.

Automatic Transmissions for Sale

Automatic transmissions are a deep mystery to most motorists. They may know the transmission requires some kind of fluid, but have probably never checked the level or even looked for the dipstick unless they drive an older vehicle with a noticeable transmission leak.

When internal problems cause your transmission to act up, it takes an expert transmission specialist with experience to diagnose the fault. If the problem is not low fluid, a faulty solenoid, valve body or controller, the transmission usually has to come out for a tear down and inspection. This can be a time-consuming process, so many shops would rather replace the transmission with a exchange rebuilt transmission when there’s a major internal problem rather than trying to repair or rebuild it themselves.

Rebuilding automatic transmissions is an exact science that requires familiarity with the unit being rebuilt as well as the correct parts, tools and specifications. If you don’t get it right the first time, you’ll certainly get the opportunity to do it over again. The shop can make more money replacing transmissions with a reman transmission purchased from an outside transmission supply company than rebuilding the units themselves. A typical FWD transmission job today can easily run $2,500 to $3,000.

One of the most common complaints with automatics is fluid leaks. Fluid can leak out of the driveshaft seals, the input shaft seal, the transmission pan gasket, the torque converter or the ATF cooler and line connections. If the fluid level gets low, the transmission may be slow to engage when it is shifted into drive. Gear shifts may be sloppy or delayed, or the transmission may slip between shifts. If the fluid level is really low, the transmission may cause the vehicle to not go at all.

If a vehicle’s Check Engine light is on, it means the computer has detected a fault and has set a diagnostic trouble code. There’s no way to know if it’s an engine code, transmission code or body code, so you’ll have to plug a scan tool or code reader into the diagnostic connector to extract the code.

If your scan tool or code reader is capable of reading transmission codes (some are not or require extra software) and you find a transmission code, what happens next depends on the code. If the code indicates an internal performance problem, the transmission will probably need the attention of a specialist. Lets leave it at that, take it to a specialist.

Electrical fault codes are set when the transmission controller or PCM detects any sort of problem with the transmission. Performance codes are set when the computer sends out a command, lets say, that the 2-3 shift has slippage.

With electrical codes, you can use a DVOM (digital volt ohm meter) to test a solenoid’s resistance. If the solenoid is open, shorted or out of specifications, it needs to be replaced. Performance codes, on the other hand, require further diagnosis and can themselves be caused by electrical faults in sensors.

Electronic transmissions use speed sensors to monitor shifts and what’s going on inside the transmission. When things don’t match up properly, a “ratio error” fault code may be set indicating something is wrong with the way the transmission is shifting gears. The only way to isolate these kinds of faults is to follow the diagnostic charts for the particular code(s). Ratio error codes often turn out to be caused by a fault in a shaft rpm sensor. Some transmission problems may require “retraining” the computer. This is also necessary if an electronic transmission or computer has been replaced.

Diagnosing your transmission before serious problems cause the need to buy a replacement transmission is of prime importance for the car owner. Time is of the essence. If you are not sure and want to speak with a professional. Call @ 866-320-1182.

The Truth behind Saturn Transmissions and Reverse Problems

Upgraded Saturn Transmissions for Sale Cheap

Upgraded Saturn Transmissions for Sale Cheap

Question: Hi, all. I have a 1993 SW2 (I know this is the SL section) with 40,000 actual miles and an auto transmission. When I shift it into reverse, it pauses, and then the transmission shifts into reverse after a lag. Often, there’s a thud also. It’s worse when cold. The car has been flat towed behind a motorhome, but before I had it.

Any thoughts will be appreciated.

My Thoughts: Since I was a transmission shop owner from 1981 to 2006, I have lots of experience with this issue. I was fortunate enough to have a man buy my shop, right out of nowhere before the economy declined so much. So, in a certain sense, I have had even more time to study transmissions.

This problem creeps up on almost every one of the automatic Saturn transmissions that reach high mileage. High mileage is usually defined as over 100,000 miles, but that will vary according to usage. When i say usage, I’m referring to your driving style depending on what your load.

A pizza delivery person runs around town in a rush, putting the car in reverse 100 times a night as they pull into and back out of driveways, using reverse a lot. Even though they may not actually put a lot of miles on the car. As opposed to a person who puts lots of miles on the car on the highway, buy does not have to use reverse very much.

Use of reverse embellishes the problem. Why is this? Because every time you put the car in reverse, it activates the reverse valve in the valve body, which strokes back and forth in the bore. The valve body is the brain of the transmission. Since the valve body is made of a very low grade cast aluminum, the actual casting is subject to wear.

It is very simple. Anytime you have a piece of metal or plastic inside a hollow bore or hole with a tight clearance between the two pieces of material you have a situation for wear. As the valve goes back and forth, from the front of the bore to the back of the bore, we have a situation where the valve or piece of material that is sliding back and forth in that area will wear the bore out, from the sliding action. That makes sense, right?

Using the crappy sand cast aluminum allows the reverse bore to wear out first. this is because reverse uses the most line pressure of any gears and therefore causes casting wear. The only true solution is to buy a brand new valve body right from the dealer along with the appropriate gaskets and have it installed by a professional. Don’t forget to refill your automatic transmission with factory approved synthetic transmission fluid.

First and foremost, have it diagnosed by a professional, or you are wasting time and money. If it turns out that your transmission is worn out anyway, you may want to look into one of our used transmissions with very low mileage, from 15,000 miles to 35,000 miles on it. has a large inventory of low mileage used transmissions that are all pre-tested for perfect function.

4T80E Cadillac Transmissions for Sale.

The Strongman of Cadillac Transmissions-4L80T for Sale

The Strongman of Cadillac Transmissions-4L80T for Sale

The 4T80-E Cadillac transmissions are one of GM’s Turbo-Hydramatic front wheel drive family of automatic transmissions or transaxles. These transmissions are well known for ruggedness and reliability.

Starting in 1966, GM had to make a dramatic change to its transmission line, when they introduced front wheel drive Oldsmobile Toronado, front wheel drive units were necessary. Cadillac received the new tranny assembly in 1967 in the front wheel drive Eldorado. The rest of the front wheel drive story is important to the history & future of automotive transmissions.

The 4L80E is designed to handle more horsepower than the lesser transmissions or transaxles, to be more accurate. Used only in Cadillacs with the powerful Northstar engine system, the 1995 to 1999 Oldsmobile Aurora Autobahn and 2005 and 2006 Pontiac Bonneville GXP.

For rebuilders, this transmission is a handful. Not only is it big, but it needs to be rebuilt with the precision of a brain surgeon. Ideally the transmission should have been diagnosed before removal. This is a benefit to the rebuilder. It is not imperative though, the rebuilders who take pride in their work take the time to do everything right, including all updates.

Without even discussing the matter, every electrical component inside the transmission should be changed with factory original components, right off the dealers shelf. Using a rebuild kit with factory original or better components and an honest, knowledgeable and well trained transmission mechanic is the recipe for success.

In reality, the removal and installation is just as important as the rebuild itself. The R&R (removal and replacement) person is removing and disconnecting wire harnesses and some expensive components which can be damaged if the R&R person is not just careful, but knowledgeable about the subject, and does not mind reading the directions if needed.

This makes flushing out the gunk in the radiator more important. In fact a good examination of the radiator and it’s supporting cast is a great idea at this point. Even superman had his weakness, and this transmission does not have many weaknesses other than performing regular maintenance using synthetic transmission fluid.

My best advise if you need to replace your Caddy Tranny is to call the transmission replacement company that outperforms all of their competition by making sure the value is literally built into your replacement transmission. By making sure we cover all of the bases for you, you can take care of buying the correct transmission fast and at an affordable price. Call @ 866-320-1182.

Top reasons for an Automotive Transmissions failure.

Keys to long automatic transmission life

Keys to long automatic transmission life

Here are the top reasons for automatic transmissions to experience a failure requiring replacement.

1. Not performing regular maintenance. Yup, it takes too long, I’ll get it done next time. Well these are bad excuses to make. You know what happens if the transmission fluid never gets changed, or you forget to change it for a year or two? It has a breakdown, or it wears out prematurely. Not cheaper in the long-run.

2. Not Coming To A Complete Stop Before Changing Directions. You’re in a rush, and you pull out of a parking space and shift into drive while the car is still coasting backwards. You’ve just added months of wear to your transmission in seconds. Inside your transmission is a complex set of gears, when you shift without stopping like that, you’re asking those gears to work as your brakes, which puts an amazing amount of stress on such a small area. It can cause immediate transmission case destruction! You can also damage your drive shafts, the things that send power to the wheels, by shifting that way.

3. Ignoring Your Car’s Sounds. Every sound your car makes means something, if you pay attention, your car can usually tell you exactly what needs fixing. Those squeaking brakes mean you need new pads, and if you ignore that sound, eventually you’ll hear scraping metal, which means you need new rotors, and if you ignore that, you’ll eventually hear the sound of your own scream as you lose your brakes completely and fly off a cliff in a spectacular fireball of death. If you see a leak from under your car, although this is a visual sign, find out what is leaking and get it fixed.

4. Driving Past Attractive Women. This is a real problem issue, especially for younger male drivers. Attractive women can be incredibly damaging to your vehicle, they can cause the driver to install bizarre over-sized woofers or 22 inch rims, or even spontaneously crash the car into a nearby tree or telephone pole. Twenty two inch rims are murder on transmissions. When you’re driving, be careful keep your eyes on the road, beautiful girls are more distracting than texting while driving!

If any of these issues is a problem for you, please feel free to call one of our rained staff members for an answer that makes sense. We sell every type of automotive transmissions at prices that can’t be beat. Every transmission we sell has value built right into it, building your confidence as an transmission consumer.

1993 Buick LeSabre Transmissions cold problem.

Rubber trees make rubber o-rings for transmissions.

Rubber trees make rubber o-rings for transmissions.

Problem: I have a 1993 Buick Lesabre with an automatic transmission problem. On cold days it takes 20 minutes to a half an hour to warm up the car before it can go forward in gear or in reverse. Now that the weather is warmer it takes about 15-20 minutes to move in gear? I know it’s the transmission but has this happened to anyone else? any suggestions from other Buick owners have had this problem?

Possibilities: To start with, this is not a Buick only problem, any car or truck using automatic transmissions (instead of manual transmissions) can experience this problem. In reality this is a hydraulic problem. Why? An automatic transmission is nothing more than a complicated hydraulic pump. It is full of rubber o-rings and seals to keep the hydraulic pressure, which is created by a pump assembly, in the proper passage ways.

An automatic transmission can produce from 60 (PSI) pounds per square inch of pressure up to over 300 PSI. That is a lot of pressure. So anything that uses rubber seals and o-rings to contain hydraulic pressure is capable of having the problems described above.

What happens to the transmission to cause this issue? Simple. The rubber seals and o-rings become brittle after getting hot and cold every time you start the car and drive it. When a compound like rubber goes through extreme temperature changes over many years, it loses it’s abilities to stay soft and supple.

What you are experiencing is hydraulic pressure pushing past the brittle seals when the transmission is cold. As the transmission gains warmth and the seals become soft and supple they can hold hydraulic pressure. The colder outside it is, the longer it takes to get the warmth to be effective.

Basically you have three choices. One choice is to move to Florida where you don’t have to deal with cold weather. Another choice is to get used to warming up your car. There is no magical cure or additive that will solve the problem, so don’t go with that avenue or you will cause more transmission damage.

The sure cure to this problem is a rebuilt transmission. The only way to cure the problem is to change the seals and o-rings. In order to do this the transmission has to be completely disassembled. Chance’s are there is plenty of wear in other transmission parts, since this is probably an older car. Especially at the mileage this problem occurs at.

With that thought in mind, the wise thing to do is contact the sales staff at and speak with a member of our company about how we can outfit you with one of our quality transmissions. 866-320-1182.

A4LD Ford Transmissions: Explorer & Ranger Rebuilt.

When the A4LD Ford transmissions were introduced in the mid 1980’s it was supposed to be a new breed of smaller overdrive automatic transmissions for up to the Ranger and Explorer sized vehicles. It was a rear wheel drive transmission. The L in A4LD stands for longitudinal which means the engine and transmission run from the front to the back of the vehicle.

When you need to replace an A4LD or it’s first predecessor the 4R44 transmission, it can be successfully rebuilt using upgrades approved by the factory and knowledgeable transmission mechanics. Successfully rebuilt means that the unit has had all of the approved upgrades installed along with the best parts available during the rebuild process.

The bottom line is that there are millions of the A4LD and 4R44 tranny’s on the road, in both old and newer Ford products through 1995 when the 4R44 was discontinued. The models that came out in 1996 were much the same except with 5 forward speeds. Many of the inherited problems were solved. Although very few parts interchange.

The update which is considered mandatory by shop owners and transmission supply companies is the usage of an approved update kit. The ones I use and recommend are made by TransGo. Google them for more information. A few other companies make fine update products, but TransGo is the oldest and the one I have the most confidence in.

During an overhaul is the best time for installation, (although you can have the bulk of the kit installed in your Ranger or Explorer without rebuilding the transmission, for much longer transmission life and better performance). If you use factory original grade rebuild parts, which is an excellent product in the first place, or better (not necessary), and use synthetic automatic transmission fluid, you have a recipe for success.

When it comes to transmissions, generic parts are not as good as name brand. When you buy a generic medicine, at least it has passed numerous standardized tests. Generic components for a transmission are not controlled like medicine, which makes many of them questionable.

Buy updated rebuilt Ford transmissions for your Ranger, Explorer, SUV or any of the other Ford products that use this transmission from Call us now and let one of our staff members help you find out why this is “where our customers send their friends”. 866-320-1182.

Slipping GMC K1500 Truck Automatic Transmissions

GMC K1500-2500 Rebuilt Truck Transmissions for Sale

GMC K1500-2500 Rebuilt Truck Transmissions for Sale

A slipping automatic transmission is the first sign of serious internal troubles heading your way. Most of the time this condition will lead to a rebuilt transmission. Here is a question about this condition as well as a good example of the likely symptoms.

Your website has allowed me to further educate myself about the engine and transmission side of cars. Here is some information about my trucks problem before I take it to a transmission shop or general car repair place.

Question: I have a 96 GMC K1500 w/ 4l65E Chevy transmission and 4WD. I am having slipping automatic transmission problems. If I drive like an old lady and ease up to Highway speeds I can feel all gears engage and pull, 1, 2, 3, and 4. If I take off hard from a stop or if I’m driving at 6Omph or more and kick it for passing gear I can see the RPM gauge jump to 3500-4000 and hear the engine running great but no power.

No codes and after a physical inspection, my fluid level is correct and no burnt odor. I have no leaks, the wiring harnesses and connectors look fine.

Because I do not have a code, can I assume that my, vss, tcs and other related sensors have no failures or intermittent shorts? My truck has over 120,000 mi on it. I think the problem is inside the slipping automatic transmission itself.

If you think the slipping transmission needs to be replaced, would you suggest any upgrades I should ask for during the rebuild?

Answer: With the high miles on your 96 GMC K1500 4WD and the age of the unit it sure does seem that internal problems would be the most likely cause of your problems. Worn lip seals allowing fluid pressure to bypass the clutch apply pistons often create a slipping condition.

You can prove it with a line pressure check with a pressure gauge connected to the test port. A stall speed test is where you power brake the vehicle (apply the gas and brake at the same time) and will verify the pressure bypassing condition.

In most cases the only way to solve this is with a complete transmission overhaul were you replace all internal seals and wear items like clutch disks and bands. The only way to determine the amount of internal damage is with a tear down and inspection.

As far as removing the transmission, you mentioned your GMC truck is a 4×4. A good thing to check when you get the truck back is the transfer case seal. The shop will have to separate the transfer case from the back of the transmission on your model. The factory makes a gasket for this sealing area. Often shops will just use rtv silicone. This is not as long lasting as a fiber gasket and tends to leak sooner or later.

If you need to purchase an upgraded rebuilt GMC transmission for your truck, let me recommend They supply the most thoroughly transmissions anywhere, using the latest upgrades available and American made Borg Warner clutch plates.

Ford Explorer Transmissions: Flashing OD Light.

Ford Explorer Transmissions: Problems!!

Ford Explorer Transmissions: Problems!!

Question: My 1996 Ford Explorer transmissions is acting up. I was driving and noticed that the Overdrive light was flashing. The transmission was operating perfectly and if the OD light was not flashing, I would have no idea that I had a problem. When I turned the truck off and restarted the light would go out.

Thanks in advance,

Also when the light is out and I press the OD button I feel it working as it did when I bought the truck new. This flashing continued so I had the code P0741 pulled from the computer. Since there was no drive ability problem, I flushed the transmission through the radiator transmission cooler and installed a TCC electronic solenoid and a new filter and gasket.

I road tested the vehicle and it shifted great as before and then the OD light started flashing again. Any suggestion?

Suggestion: A. There may be several reasons for this problem. First, Ford has issued a TSB (technical service bulletin) on this problem. It has to do with a transmission oil pump defect and repair procedure.

Article No.: 97-22-4
Date: 10/27/97

Transmission – A4LD, 4R44E/4R55E, 5R55E – Torque Converter Slip – Diagnostic Trouble Code (DTC) 628 Or P0741 Stored In Memory

1985 to 1993 Mustang
1987 to 1988 Thunderbird

1988 Cougar

Light Truck:
1985 to 1990 Bronco II
1985 to 1997 Ranger
1987 to 1997 Aerostar
1991 to 1997 Explorer

Some vehicles may experience excessive torque converter slippage, torque converter not engaging, or Diagnostic Trouble Code (DTC) 628 or P0714 stored in memory. This may be caused by damage to the fluid pump support seal and/or to the groove on the pump where the seal is located.

Inspect the fluid pump seal for damage. Refer to the following Service Procedure for details.

1. Follow normal diagnostic procedures as listed in the appropriate Service Manual.
2. Inspect the fluid pump support for damage. If damaged, also inspect the fluid pump support seal groove on the pump.
3. If the groove is damaged, replace the pump.
4. If the groove is not damaged, replace the fluid pump support seal with a redesigned Seal (F77Z-7L323-AA). Refer to Figure 1.
5. Do not replace the torque converter unless it is damaged or fails the criteria listed in the appropriate Service Manual and/or refer to TSB 96-26-12.

This is something I recommend having a Ford Dealer do since they have the experience with it. Depending on the mileage and overall condition of your transmission, if and when this occurs will help you decide if fixing your transmission is worth it over replacing it. In most cases, if your car is older and has lots of miles on it, you may save time and money and cure your problem by buying a used transmission or rebuilt transmission as an option.

Realistically speaking, once a transmission wipes out the pump, and more importantly other areas of the transmission, repairs are not a viable option. If you are in this exact situation and need some counseling, call at 866-320-1182 and speak with a member of our staff about which replacement transmissions may be in your best interests.

Chevrolet Epica 6 speed automatic transmission.

Chevy transmissions for sale

Chevy transmissions for sale

A completely new six-speed automatic transmission now is available for Chevrolet Europe’s top sedan. The Epica offers the space and drive comfort of the upper medium class but at a much lower price. Chevrolet’s dedication to refinement is illustrated with the new gearbox which can be mated to all three engines (2.0 L/143 hp, 2.5 L/156 hp, 2.0 D/150 hp).

The wide 6.14:1 overall ratio of Chevrolet Europe’s six-speed automatic transmissions optimizes engine use and delivers improved fuel economy at high speeds compared to typical four-speed automatic transmissions. It also offers smooth, seamless upshifts and down-shifts.

Owing to a overdrive sixth gear, the Epica 2.5 equipped with the new transmission delivers up to 15 percent better fuel economy when constantly driven at 90-120 km/h compared to its predecessor with a five-speed automatic transmission. Additionally, the transmission improves 0-40 km/h and 0-60 km/h performance of the Epica by up to 10 percent, respec-tively.

The new transmission has small steps between its six forward gears. In combination with the wide overall ratio, this also enables a steep 4.58:1 first gear, which helps deliver improved launch and acceleration while ensuring dynamic driving at lower speeds. The small steps also enable a 0.75:1 overdrive sixth gear. This “tall” overdrive gear reduces engine rpm at highway cruising speeds, thereby reducing engine wear and improving fuel economy.

Chevrolet Europe offers two variants of the Hydra-Matic six-speed automatic transmission. The 6T40 for inline six-cylinder gasoline engines and the 6T45 for higher-torque diesel en-gines. Despite the higher number of gears, both variants are the size of a conventional four-speed transmission, making them among the most compact in their competitive classes.

The compact size has been made possible in part by the mechanical simplicity of the trans-missions’ advanced clutch-to-clutch operation, which provides smooth shift feel and pack-aging efficiency. This is achieved through the utilization of three planetary gears, three sta-tionary clutches and two rotating clutches.

A 32-bit intelligent controller included in a sophisticated internal Transmission Electro-Hydraulic Control Module (TEHCM) is mounted inside the transmissions, reducing vehicle complexity. The unit operates while bathed in transmission fluid, which protects it from external percussion’s and facilitates modular design and assembly.

A compact on-axis, fixed-displacement IX Gear-type fluid pump lowers noise, vibration and harshness levels and improves hydraulic efficiency. Electronic safeguards prevent improper shifting, which could damage the engine or affect vehicle control.

The use of DEXRON®-VI synthetic premium transmission fluid, which has a more consistent viscosity than similar fluids on the market, further improves durability and shift stability, resulting in improved torque transfer and shift performance.

Making the correct choice in replacement transmissions is one way we provide added help to our customers in need. Our trained sales staff is prepared to answer your questions and help you choose the transmission that is your best interests. Call @ 866-320-1182.

Best Selling Cars in America have Automatic Transmissions

Transmissions for sale

Transmissions for sale

The Nissan Sentra was the best selling car in America in February of Two Thousand Ten. The Chevy Impala was the second best selling car in February of 2010. Both cars have two things in common, sales up 50% in February 2010, and both cars have automatic transmissions as the standard choice. Sales being up is not a surprise with Toyota having issues. Automatic transmissions have been the choice over manual transmissions for years now.

The Nissan Sentra front-wheel drive 4-door sedan is a practical, roomy and economical car with several trims available to suit a person’s needs.

The 2.0, 2.0S, 2.0SL, 2.0SR, SE-R, and the SE-R Spec V.

The 2.0-liter four-cylinder engine produces 140-hp and is mated to either a six-speed manual or a continuously variable transmission.

The SE-R and SE-R Spec V both have a 2.5-liter four-cylinder engine which produces 177-hp in the SE-R and 200-hp in the Spec V.

The SE-R is offered only with a CVT transmission, while the Spec V is paired with a six-speed manual transmission.

Automatic transmissions are becoming the clear choice in transmission options for several reasons. One reason is that with the new technologies in the way they operate, increases fuel mileage over a manual transmission. Working hard to meet fuel mileage requirements is part of the reason for added speed ranges and improved shift quality and torque converter operation.

More speeds and improved shift quality for automatic transmissions has attracted many of the old school manual transmission people. Now you can achieve the shiftless performance of an automatic trans., or grab the shifter and use it as a standard. The newer Porsche’s and some of the BMW’s have super hi-technology automatic gearboxes, which are capable of some serious racing and excellent street manners on the way home.
