•
Regulated oil pressure is supplied to the clutch when the selector lever is moved from
N to D or from N to R, after the engine started.
Reverse control
•
If the selector lever is moved from N to R while the vehicle is traveling and the transaxle
shifts into reverse, TCM inhibits the transaxle from shifting into reverse while traveling.
Engine-transaxle total control
•
Optimally controls engine output torque when shifting.
•
Operates optimal clutch engagement pressure corresponding to engine output torque.
On-board diagnostic system
•
Detects and/or memorizes failure of input/output part and transaxle condition.
