AT5032
(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 mecha-
nism 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.
NOTICE: Special handling methods are necessary for full-time 4WD vehicles during inspection and
maintenance. Instructions concerning these handling methods are given on Camry Repair Manual
(Pub. No. RM199U) on page IN-8.

REMOVE VEHICLE SPEED SENSOR
(a) Remove the bolt and pull out the speed sensor.
(b) Remove the O-ring from speed sensor.
10. REMOVE OIL PAN AND GASKET
(a) Remove the seventeen bolts.
(b) Remove the oil pan by lifting transaxle case.
NOTICE: Do not turn the transaxle over as this will
contaminate the valve body with the foreign materials
in the bottom of the oil pan.
(c) Place the transaxle on wooden blocks to prevent
damage to the oil tube bracket.
11. EXAMINE PARTICLES IN PAN
Remove the magnet and use it to collect any steel chips.
Look carefully at the chips and particles in the oil pan
and on the magnet to anticipate what type of wear you
will find in the transaxle.
Steel (magnetic)... bearing, gear and plate wear
Brass (non-magnetic)... bushing wear
