TRSM0940 Service Procedures | LAS/VAS Auxiliary Section Assembly and Installation 
4. Once the Auxiliary Case is pushed as far into the Trans-
mission Main Case as possible, remove the Auxiliary 
Section Lifting Bracket. Loosen
 the Auxiliary Counter 
Shaft Support Strap cap screws and fully seat the Aux-
iliary Case to the Transmission Main Case.
Note: Fully 
seating the Auxiliary Section to the Trans-
mission Main Case should take light force; do not draw 
it in with bo
lts. If the Auxiliary Section will not come 
flush with the Transmission Main Case, a timing issue 
with the Auxiliary Section gearing may be the cause.
5. Install 
the 16 cap screws that fasten the Auxiliary Sec-
tion to the Transmission Main Case. Torque bolts to 
35–
45 lb-ft.
LAS/VAS Auxiliary Counter Shaft Shimming
1. Remove the Auxiliary Counter Shaft Support Straps 
and install a 0.100" shim between the cover and Auxil-
iary Counter Shaft. Use two of the Counter Shaft Bear-
ing Cover bolts and torque bolts to 7 lb-in. Spin the 
Output Shaft multipl
e times to assist in seating the 
bearing races. Ensure cap screws are still torqued at 7 
lb-in.
2. Using feeler 
gages, measure the gap between the Aux-
iliary Counter Shaft Covers and the Auxiliary Case. Use 
multiple positions closest to 
the cap screws.
