(11)
Install the third clutch piston assembly into the center support. The lips of the seal rings must be toward
the cavity in the center support.
Improper installation of butt-joint seal rings may cause transmission failure. If humidity is allowed to
penetrate and expand the butt-joint seal ring, the seal ring can be damaged during installation. A
damaged seal ring will leak oil from the clutch piston cavity and cause clutch3-75 slippage. Do not open
the sealed package until you are ready to install the seal ring.
