Loctite 518 to seal the cover.
Procedures for the serviceable components in the
shift cover as follows:
Fifth-Reverse Shift Fork Pal Replacement
The plastic shift fork pads are held in place by a
combination of tension and a small locating tang.
Three pads are used on the fork (Fig. 164).
The pads can be removed either by hand or with a
narrow blade screwdriver. To remove the pads by
hand, grasp each pad and tilt it out and off the fork.
If the pads prove difficult to remove by hand, insert a
screwdriver blade between the pad and fork and pry
the pad off.
