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.

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
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
