• D-ring might be damaged.
• Seal lip might be damaged.
• Fluid might be leaking past piston check ball.
2. Remove snap ring (1) using a flat-bladed screwdriver A.
3. Remove retaining plate, drive plates, driven plates and dish
plates.
4. Set Tool A on spring retainer assembly, and remove snap ring
(1) from reverse clutch drum while compressing spring retainer
assembly.
CAUTION:
Set SST directly over return springs.
5. Remove spring retainer assembly from reverse clutch drum.

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.
