Transmission Case Installation

Tools Required:
^ J 41099 Reverse Solenoid Socket
^ J 36850 Transmission Assembly Lubricant

Important: Lubricate all components as the assembly progresses, using the J 36850 or the equivalent.





1. Apply sealant GM P/N 12345739 or the equivalent, to the transmission case to adapter plate mating surface.





2. Install the ball detent and the spring in the front offset lever.




3. Do the following in order to install the transmission case and the offset lever:

3.1. Shift the transmission into NEUTRAL in order to keep the 3rd /4th shift shaft from engaging.

3.2. Install the offset lever.

3.3. Compress the front offset lever together while sliding it onto the shift shaft. This will prevent the spring release of the inner components.

3.4. Slide the transmission case onto the gear clusters and the shift rail components.





4. Apply anaerobic threadlocker GM P/N 12346004 or the equivalent to the threads of the shift lever guide bolts.
