SPECIAL INSTALLATION NOTE:
The rear output shaft bearing that is located in the back of the transmission main case has an external snap ring around
the outside diameter of the bearing. The snap ring is trapped between the transmission case and the new housing. By
trapping the snap ring, the main shaft location is held in a firm location and the shaft is prevented from drifting either
forward or rearward. The thickness of the original snap ring varies between a 2WD GM transmission and a 4WD GM
transmission. Since we use the same adapter housing for both locations, it may be necessary to modify the thickness of
the snap ring for installation with the new adapter housing. This can be done by simply grinding down the thickness or
by doubling up on the gasket between the transmission and the transfer case. Not all applications will have this problem,
but you should be aware of this variation. Two wheel drive transmissions use a thinner snap ring.
