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

Advance Adapters 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.

NOTE: Crossmember block may need to be shortened to fit on

stock rubber crossmember on certain applications.
