Question: Have 2000 Infiniti G20, ~ 30 K miles on it.
Car was running fine, got 25 MPG all the time.
After the 30K mile service visit, the tranny started slipping.
MPG is now ~ 21 MPG. The tranny slipping is intermittent, and after a severe episode the overdrive light will flash for about 5 to 10 seconds.
Took it back to dealer. They found no problem, didn’t seem to know what the flashing OD lite means, and charged $160 for a flush and fill on the tranny!
It is still happening. Called Infiniti, and they will not say what the flashing light means- must rely on dealer to diagnose problem.
Answer: The transmission entered self-protection mode or safe mode. This could be triggered by overheat or slippage, etc. There are definitely problems with the transmission. OD flashing should mean the transmission control unit has detected something wrong – just like check engine light.
You don’t say if they flushed the transmission out when the 30,000 mile service visit was performed. Either way flushing your transmission out before they figure out the problem is a scape goat and shows how incompetent that dealer is. I would try another dealer.
The bottom line is this, I keep saying it too. The problem has to be diagnosed using the proper technical procedures and diagnostic tools. I would be very direct and forward about diagnosing the problem. It is preposterous for a dealer to not have a trained transmission mechanic who knows how to diagnose the problem.
Obviously they don’t care to build a good relationship with you. If you don’t find a competent transmission shop to diagnose and fix this problem ASAP, I guarantee you will be looking at a rebuilt Infinity transmission soon. Get it diagnosed and fixed, then take it up with the dealer.
Diagnosing a car is much like having an ailment concerning your health diagnosed. When you have a health issue, you can’t call a doctor and ask him what’s wrong with you, you have to make an appointment so he can examine you. Mechanics, technicians, dealers, non of us have super powers that make it possible to diagnose without having the patient or car in this case.
