3. Disconnect terminal cord assembly harness connector.
4. Remove snap ring from terminal body.
5. Remove terminal cord assembly by pushing terminal body into
transaxle case.
6. Remove engine under cover.
7. Remove front LH nut of front suspension member, and then
lower front LH of front suspension member to secure a space for
removing control valve assembly.
8. Drain ATF from A/T. Refer to AT- 1 5 , "
Changing A/T Fluid" .
9. Remove oil pan and oil pan gasket.
10. Check foreign materials in oil pan to help determine causes of
malfunction. If the ATF is very dark, smells burned, or contains
foreign particles, frictional 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 frictional material is detected, replace radiator after
repair of A/T. Refer to CO-13, "
RADIATOR" , CO-16,
"RADIATOR (ALUMINUM TYPE)" (QR engine) or CO-37,
"RADIATOR" , CO-40, "RADIATOR (ALUMINUM TYPE)"
(VQ engine).
11. Remove control valve assembly fixing bolts A, B and C .

a. Blow air into the oil hole as shown in the figure 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 oil. Cover the area with lint-free
paper and blow air little by little to avoid this.

Wrap the removed accumulator piston in a lint-free paper.
b. Remove O-ring from servo release accumulator piston.
c. Blow air into the oil hole shown in the figure 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 oil. Cover the area with lint-free
paper and blow air little by little to avoid this.

Wrap the removed accumulator piston in a lint-free paper.
d. Remove O-ring from N-D accumulator piston.
17. Remove lip seals from oil groove for band servo.
18. Remove magnets from oil pan.
Inspection

Check the contact surface of each accumulator piston and tran-
saxle case, and replace if damaged or dented.

Check the sliding surface of manual valve and valve body, and
replace if damaged or dented.

Check each return spring, and replace if damaged, deformed or
worn. Refer to AT- 3 6 5 , "
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
Note the following, and install in the reverse order of removal.

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

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

After completing installation, check for leakage, and A/T fluid
level. Refer to AT- 1 4 , "
Checking A/T Fluid" .
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
fitting bolts.

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