109. Clean and inspect the overdrive/direct clutch hub and shaft assembly for damage. Install new, if necessary.

110. Install the direct clutch wave spring.





111. Lubricate the direct clutch pack in clean transmission fluid.





112. Install the direct clutch assembly and pressure plate.





113. Install the direct clutch snap ring.





114. Install new direct clutch piston seals and lubricate the seals with petroleum jelly.





115. Install the direct clutch piston return spring.





116. Lubricate a new direct clutch piston with petroleum jelly and install the piston.





117. Install a new rear direct clutch cylinder seal and lubricate it with petroleum jelly.





118. Install the direct clutch cylinder.





119. NOTICE: Only compress the direct clutch piston return spring far enough to install the direct clutch cylinder snap ring. If the direct clutch cylinder is pressed too far, the direct clutch cylinder alignment tab may be broken off. The tab is used to align the TSS (Turbine Shaft Speed) sensor tone wheel (part of the direct clutch cylinder). If the tab is broken, erratic shifts and transmission damage can occur.

NOTE: Align the tab on the direct clutch cylinder with the slot on the overdrive/direct clutch hub and shaft assembly.

Install 307-589/2 and 307-584/2 on the direct clutch cylinder. Using a press, compress the direct clutch piston return spring and install the snap ring.
