A-4- SERVICE SPECIFICATIONSAutomatic Transaxle Transfer (A540E A540H)

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.

(e) Remove the overdrive clutch apply gasket and
overdrive brake apply gasket.
47. REMOVE FIRST AND REVERSE BRAKE PISTON
(a) Remove the piston return spring.

Place SST, and compress the return spring
evenly by tightening the bolt gradually.
SST 09350-32014 (09351-32040)

Using snap ring pliers, remove the snap ring.

Remove SST.

Remove the return spring from the case.
(b) Apply compressed air into the passage of the case
to remove the piston.
HINT: Hold the piston so it is not slanted and blow with
the gun slightly away from the oil hole.
(c) If the piston does not pop out with compressed
air, use needle-nose pliers to remove it.

DISASSEMBLY OF OVERDRIVE BRAKE
1. REMOVE PISTON RETURN SPRING
(a) While pushing the return spring, remove the snap
ring with a screwdriver.
(b) Remove the piston return spring.
2. REMOVE PLATES, DISCS AND FLANGE
3. REMOVE PISTON FROM DRUM
Apply compressed air to oil hole to remove the piston.
HINT: Blow with the gun slightly away from the oil hole,
and be careful that the piston dose not tilt.
4. REMOVE O-RINGS
Remove the inner and outer O-rings from the piston.
INSPECTION OF OVERDRIVE BRAKE
INSPECT DISCS, PLATES AND FLANGE
Check if the sliding surfaces of the discs, plates and
flange are worn or burnt. If necessary, replace them.
HINT:

If the lining of the disc is exfoliated or discolored,
or even a part of the printed numbers are defaced,
replace all discs.

Before assembling new discs, soak them in ATF
for at least fifteen minutes.

3. INSTALL OVERDRIVE PLANETARY RING GEAR INTO
COUNTER DRIVE GEAR
(a) Install the snap ring to the ring gear.
(b) While pushing down the ring gear, squeeze the
snap ring end with needle-nose pliers, and install
it into the groove.
4. INSTALL REAR BEARING
Using SST, press in the bearing onto the shaft.
SST 09350-32014 (09351-32120)
HINT: Press in the bearing until the side surface of the
inner race touches the planetary carrier.
5. INSTALL COUNTER DRIVE GEAR AND FRONT
BEARING
(a) Install the gear onto the shaft, and mesh the ring
gear with the planetary pinions.
(b) Place the front bearing onto the shaft.
(c) Using SST, press in the bearing until slightly play
between the bearings.
SST 09350-32014 (09351-32120)
HINT: Hold the ring gear to prevent it from falling.

Using SST, press in the bearing until it slightly touches
the front bearing of the counter drive gear.
SST 09350-32014 (09351-32120)
HINT: The counter drive gear can be turned lightly.
7. PLACE NEW LOCKING WASHER
8. INSTALL ADJUSTING NUT AND ADJUST PRELOAD
OF COUNTER DRIVE GEAR
(a) Hold the overdrive planetary gear in a vise with
soft jaws.
(b) Using SST, tighten the adjusting nut until the fol-
lowing gear starting load is reached on the ten-
sion gauge.
SST 09350-32014 (09351-32080)
Preload (at starting): 940-1,560 g
(2.1-3.4 lb, 9.2-15.3 N)
HINT: Turn the counter drive gear right and left several
times before measuring the preload.
(c) Lock the adjusting nut with one tab on locking
washer. Bend the locking washer tab until it is
even with the adjusting nut groove.
9. INSTALL NO. 3 OVERDRIVE PLANETARY THRUST
WASHER
10. INSTALL PINION SHAFT PLUGS
Install the four plugs into the pinion shaft.
