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.

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.
