This gearbox features a 3.06 first gear ratio for great acceleration and a 0.70 overdrive fourth gear ratio improved fuel economy. The high stall torque converter produces a stall speed of approximately 2300 RPM behind most small-block engines. The output shaft does not contain provisions for a mechanical speedometer application. The production use of this transmission assembly was for the police package 350 Vortec powered Chevrolet Tahoe.
For proper transmission operation for both carbureted and fuel injected applications a control module and wiring harness is also available separately. 4L60E gear ratios: 1st 3.06, 2nd 1.75, 3rd 1.00, 4th 0.70.
Being one of the best and most versatile transmissions ever made has made this transmission an all time popular unit with General Motors vehicle owners. The great gear ratios make it suitable for your Camaro or a Chevy 1500 series work truck. The difference lies in how the transmission computer (TCU), is programmed. Every vehicle has it’s own program in the computer.
With that in mind, it becomes essential to get the exact replacement transmission for your car. You certainly don’t want a truck transmission in your Buick, it may physically fit, but it is programmed to shift hard, like a truck.
Receiving the exact replacement transmission is the way to go. In order to make sure you get a truck transmission for a truck and a Buick transmission for a Buick, number one you have to have your vehicle identification number, and number two, you need to have some confidence in who you deal with.
