REMOVAL AND INSTALLATION
Removal
1. Disconnect the battery negative terminal.
2. Remove engine under cover and fender protector (LH). Refer to EI-23, "
Removal and Installation".
3. Drain the A/T fluid. Refer to AT- 1 5
.
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.
6. Remove magnets from oil pan.

REPAIR FOR COMPONENT PARTS
a. Apply compressed air into oil hole of transaxle case at the loca-
tion as shown in the figure.
b. Check to see that retaining plate moves to snap ring.
c. If retaining plate does not contact snap ring:
• D-ring might be damaged.
• Seal lip might be damaged.
2. Remove snap ring (1) using a flat-bladed screwdriver A.
3. Remove retaining plates, drive plates, driven plates, dish plates.
4. Set Tool A on spring retainer assembly, and remove snap ring
from transaxle case while compressing spring retainer assem-
bly.
CAUTION:
Set SST directly over return springs.
5. Remove spring retainer assembly from transaxle case.
CAUTION:
Do not remove return springs from spring retainer.
6. Apply compressed air into the oil hole on transaxle case as
shown in the figure to raise piston while strongly pressing the
whole low & reverse brake piston by hand. When applying com-
pressed air, strongly press the whole piston and adjust the pres-
sure so that it is raised evenly. Portion (A) (low & reverse brake
pressure) especially tends to tilt.
CAUTION:
Apply air gradually and allow low & reverse brake piston to
come out evenly.
7. Remove low & reverse brake piston from transaxle case by turn-
ing it.
8. Inspect transaxle case. Replace if damaged or worn.
