CONTROL SYSTEM

• Check for foreign materials in oil pan to help determine causes of

malfunction. If the ATF is very dark, smells burned, or contains for-
eign particles, frictional material (clutches, band) may need
replacement. A tacky film that will not wipe clean indicates varnish
build up. Varnish can cause valves, servo, and clutches to stick
and can inhibit pump pressure. 

- If frictional material is detected, flush the A/T fluid cooler after

repair of A/T. Refer to 

TM-172, "A/T Fluid Cooler Cleaning"

.

• Remove servo release accumulator piston and N-D accumulator

piston by applying compressed air if necessary.

CAUTION:

Hold each piston with lint-free paper.

- Apply compressed air to the oil hole as shown, and remove servo

release accumulator piston from transaxle case.

CAUTION:

Strong flow of air will push the accumulator piston out along
with a splash of ATF. Cover the area with lint-free paper and
blow air little by little to avoid this.

- Apply compressed air to the oil hole as shown, and remove N-D

accumulator piston and return spring from transaxle case.

CAUTION:

Strong flow of air will push the accumulator piston out along
with a splash of ATF. Cover the area with lint-free paper and
blow air little by little to avoid this.

- Remove O-rings (1) from servo release accumulator piston (2) and

N-D accumulator piston (3).

CAUTION:

Wrap the removed servo release accumulator piston (2) and
N-D accumulator piston (3) in a lint-free paper.

INSPECTION

• Inspect the sliding surfaces of each accumulator piston and tran-

saxle 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 

TM-321, "Accumulator"

 for free length (L

1

) and

length (L

2

).

(1): Return spring (Servo release accumulator)
(2): Return spring (N-D accumulator)

CAUTION:

Do not remove spring retainer (3).

INSTALLATION

Install is in the reverse order of removal.

CAUTION:

• Completely remove all moisture, oil and old gasket, etc. 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 transaxle case.

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 

TM-171, "Checking A/T Fluid"
