Pump Indexing
Pump must be correctly indexed to correspond with
engine rotation. If pump is not indexed correctly,
pump will not create oil pressure and transmission
will not shift. Pump housing has two arrows, each
pointing in a different direction. Pump must be posi-
tioned so that the arrow (pointing in the direction that
input shaft and pump will be turned by engine) is at
the top of transmission.
IMPORTANT: Some transmissions have letters
“RH” and “LH” on pump housing. Letters DO
NOT indicate engine rotation.
If pump must be re-indexed, proceed as follows:
1. Remove four pump attaching bolts.
2. Loosen the pump housing. A soft tip mallet may
be used to tap the fluid passage boss. Do not
strike the bolt bosses.
IMPORTANT: Do not remove the pump from the
shaft unless a seal protector is used to prevent
the shaft splines from cutting the pump seal.
Care must be taken to ensure that seal, gasket,
seal and bolt bosses are kept in good condition
to prevent leaks in those critical areas.
3. Make sure that pump gasket is not sticking to
housing (to prevent gasket from tearing or fold-
ing) when rotating pump.
4. Rotate pump until arrow indicating the proper di-
rection of pump rotation is near the top of trans-
mission.
5. Reinstall four pump-to-adaptor attaching bolts
and torque to 204-264 lb. in. (23-29 N·m).
