Place piston in the piston cavity of housing. Be sure it is firmly bottomed in the cavity.
Install twenty-eight springs into their recesses in the piston. Install retainer, so the offset tangs are
upward, onto the piston and springs. Aline the holes in the tangs with the bosses on the piston.
Failure to install the retainer rings properly can result in transmission damage or malfunction. If installed
too far onto the risers, proper clutch clearance cannot be obtained. If not installed far enough, the
retainers may fall off.
Using installer J24453, install four retainer rings. Press each ring into place until the adjacent retainer
tang bottoms in the counterbore of the adapter housing.
When all four retainer rings are properly installed, remove the piston assembly from the adapter housing.
Lubricate seal rings with transmission fluid (item 9, Appendix B). Install the seal rings, with the lip of each
seal ring facing rearward, away from the spring side of the piston.
Install the piston assembly into the adapter housing, being very careful to avoid folding the seal lips back
upon themselves. If any difficulty is encountered, remove the piston, and check the seals and housing
bore before again attempting installation.
