REMOVAL AND INSTALLATION
Removal 1. Disconnect the battery negative terminal.
2. Remove engine under cover and fender protector (LH). Refer to EI-24, " Removal and Installation " .
3. Drain the A/T fluid. Refer to AT-17 .
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-38 .

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 pu sh 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 pu sh 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 rel ease accumulator piston (2) and
N-D accumulator piston (3) in a lint-free cloth.
16. Remove lip seals (1) from transaxle case.
Inspection • Inspect the sliding surfaces of each accumulator piston and tran- saxle case, and replace if damaged or dented.

(2): N-D accumulator piston
• Inspect the sliding surfaces of manual valve and valve body, and replace if damaged or dented. SAT020D

Installation
Installation is in the reverse order of removal.
CAUTION:
• Completely remove all moisture, oil and old gasket from the oil pan gasket mounting surface of tran-
saxle 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, li p seals and sliding surfaces of the transaxle case.
NOTE:
• Set manual shaft in “N” position, then align manual plate (1) with
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-17, " Checking A/T Fluid " .
