- Locating tab on rear side of cover must be inserted into small hole on transmission surface.
- Push selector shaft lever -2- completely toward front until it stops so that shifting cam -1- stands almost vertically (with slight tilt toward right).





- Press control piston -B- on rear side of hydraulic control assembly completely inward (left) until it engages into assembly spring -A-.
- Insert hydraulic control assembly into transmission without canting it.

Note:
^ When installing hydraulic control assembly, make sure that shifting cam (item 1 in Fig. A38-0094) engages into free groove -arrow- on control piston -B-.





- Thread in bolts -arrows- hand-tight. Bolt -arrow 1- is shorter than the other two bolts.
- Check cover for correct seating. Locating tab -B- must be inserted into hole intended for it on the transmission.





Checking operation of control piston -B-
- Move selector shaft at detent plate -C- or at selector shaft lever several times toward left and right.
^ Control piston -B- must travel outward and inward accordingly -arrow-.





If control piston does not move, shifting cam has not engaged into groove -arrow- at control piston on rear side of hydraulic control assembly. If this occurs:
