For 1990-2009 cars

The 4T60-E is a fully automatic front wheel drive transmission. The 4T60-E provides four forward ranges including overdrive.

You can operate the transmission in any one of the following seven modes:

• | P--Park position prevents the vehicle from rolling either forward or backward. For safety reasons, use the parking brake in addition to the park position.

• | R--Reverse allows the vehicle to be operated in a rearward direction.

• | N--Neutral allows the engine to be started and operated while driving the vehicle. If necessary, you may select this position in order to restart the engine with the vehicle moving.

• | OD--Overdrive is used for all normal driving conditions. Overdrive provides four gear ratios plus a converter clutch operation. Depress the accelerator in order to downshift for safe passing.

• | D--Drive position is used for city traffic, hilly terrain and trailer towing. Drive provides three gear ranges. Depress the accelerator in order to downshift.

• | 2--Manual second provides acceleration and engine braking. You may select this range at any vehicle speed.

• | 1--Manual Lo provides maximum engine braking. You may select this range at vehicle speeds under 40 mph (65 km/h). Manual Lo is not available on some models.
