Inspection

Inspect the sliding surfaces of each accumulator piston and
transaxle case, and replace if damaged or dented.
(1): Servo release accumulator piston
(2): N-D accumulator piston

Inspect the sliding surfaces of manual valve and valve body, and
replace if damaged or dented.

Inspect each return spring, and replace if damaged, deformed or
worn. Refer to AT-380, "
Accumulator" for free length (L1 ) and
length (L
2 ).
(1): Return spring (Servo release accumulator)
(2): Return spring (N-D accumulator)
CAUTION:
Do not remove spring retainer (3).
Installation
Installation is in the reverse order of removal.
CAUTION:

Completely remove all moisture, oil and old gasket from the oil pan gasket mounting surface of
transaxle case and oil pan.

Do not reuse O-rings, lip seals, oil pan gasket and oil pan bolts.

Apply ATF to manual valve, O-rings, lip seals and sliding surfaces of the transaxle case.
NOTE:

Set manual shaft in “N” position, then align manual plate (1) with
groove in manual valve (2).

After installing control valve assembly to transaxle case, make
sure that selector lever can be moved to all positions.

After completing installation, check for A/T fluid leakage and A/T
fluid level. Refer to AT- 1 6 , "
Checking A/T Fluid" .

Installation is in the reverse order of removal.
NOTE:

Drive each differential side oil seal evenly using a drift (SST and
commercial service tool) so that differential side oil seal pro-
trudes by the dimension “C” or “D” respectively.
(1): LH differential side oil seal
(2): RH differential side oil seal
(A): Transaxle case side
(B): Converter housing side
Unit: mm (in)

Differential side oil seal pulling direction is used as the refer-
ence.
Drift to be used:

After installing differential side oil seal, check A/T fluid leakage and A/T fluid level. Refer to AT- 1 6 , "Check-
ing A/T Fluid" .

CVT FLUID CHECK
Fluid Leakage and Fluid Level Check

Inspect for fluid leakage and check the fluid level. Refer to CVT-16, "Checking CVT Fluid" .
Fluid Condition Check
Inspect the fluid condition.
STALL TEST
Stall Test Procedure
1. Inspect the amount of engine oil. Replenish the engine oil if necessary.
2. Drive for about 10 minutes to warm up the vehicle so that the
CVT fluid temperature is 50 to 80°C (122 to 176°F). Inspect the
amount of CVT fluid. Replenish if necessary.
3. Securely engage the parking brake so that the tires do not turn.
4. Install a tachometer where it can be seen by driver during test.

It is good practice to mark the point of specified engine
rpm on indicator.
5. Start engine, apply foot brake, and place selector lever in “D”
position.
