device assembly.
CAUTION:

Do not bend or twist key interlock cable excessively
when installing.

After installing key interlock cable to cable bracket (D) on
control device assembly, make sure casing cap (C) is
firmly secured in cable bracket (D) on control device

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" .

a. 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. To avoid this cover the area with
lint-free cloth and blow air little by little.
b. 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. To avoid this cover the area with
lint-free cloth and blow air little by little.
c. 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

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" .
