Transaxle Description
This automatic transaxle is a 4-speed, front wheel drive automatic transaxle with electronic controls for
- electronic pressure control (EPC) solenoid for shift quality.
- shift scheduling.
- 3-2 shift timing.
- coast braking.
- torque converter clutch control.
The transaxle features a 4 element torque converter with a torque clutch and a geartrain that includes
- compound planetary gearset.
- chain drive.
- planetary gearset final drive.
- pinion and side gear differential.
The hydraulic control system of the transaxle has 5 solenoids that control
- shift feel, through line pressure control.
- shift scheduling, through shift valve positioning control.
- modulated application of the torque converter clutch.
- timing of 3-2 shifts.
- engine braking during coast operation.
When servicing the automatic transaxle, refer to the IDENTIFICATION TAG located on the case.
