REMOVAL AND INSTALLATION
Removal
1. Disconnect the battery negative terminal.
2. Remove engine under cover and fender protector (LH). Refer to EI-22, "
Removal and Installation" .
3. Drain the A/T fluid. Refer to AT-16, "
A/T FLUID" .
4. Remove oil pan and oil pan gasket.
5. Check for foreign materials in oil pan to help determine cause of
malfunction. If the ATF is very dark, smell burned or contains for-
eign particles, friction material (clutches, band) may need
replacement. A tacky film that will not wipe clean indicates var-
nish build up. Varnish can cause valves, servo, and clutches to
stick and can inhibit pump pressure.

If ATF contains frictional material (clutch, bands, etc.),
replace radiator and flush cooler line using cleaning sol-
vent and compressed air after repair of A/T. Refer to CO-
11, "RADIATOR" .
6. Remove magnets from oil pan.

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" .

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" .
