Install the low and reverse brake piston.
(1) Apply ATF to the inner and outer seals, and
install them to the low and reverse brake piston.
(2) Face the outer seal lip toward the inside by
gently rolling it down around the circumference
for easier installation into the case.
(3) Install the low and reverse brake piston by
pushing evenly around the circumference, be-
ing careful not to damage the outer seal.

(5) Install the SST in the case.
(6) Compress the spring and retainer assembly.
(7) Install the snap ring with snap ring pliers.
(8) Remove the SST.
6. Check the low and reverse brake piston operation.
(1) Pour in ATF so that the low and reverse brake
piston is fully submerged.
(2) Check that no bubbles come from between the
piston and seals when applying compressed
air through the fluid passage. (Refer to page
7B—204)
Caution
