Pump Indexing
5.   Reinstall  four pump-to-adaptor  attaching  bolts
and torque to 204-264 lb. in. (23-29 N·m).
Pump must be correctly indexed to correspond with
engine  rotation. If  pump  is  not  indexed correctly,
pump will not create fluid pressure allowing the trans-
mission to 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.
