Description

GENERAL




(A540H)
The A540H automatic transaxle design is based on the A540E automatic transaxle and equipped with a center differential and transfer.

This transaxle has the same hydraulic multiplate clutch in the center differential limiting control mechanism as the A241H automatic transaxle on the Corolla ALL-Trac/4WD Station Wagon. The fluid pressure acting on the hydraulic multiplate clutch of the A540H is controlled by the ECT ECU (Electronic Control Unit) according to the vehicle driving conditions. As a result torque is distributed to the front and rear wheels appropriately at all times to maximize the overall performance of the 4WD vehicle.

NOTE: Special handling methods are necessary for full-time 4WD vehicles during inspection and maintenance.
