NOTE:
THIS BULLETIN APPLIES TO VEHICLES EQUIPPED WITH A STANDARD DUTY OR HEAVY DUTY NV4500 MANUAL TRANSMISSION.
DISCUSSION:
When disassembling the NV4500 manual transmission, it is necessary to replace the 5th gear mainshaft nut (shown in illustration). Before installing the nut, Mopar Lock & Seal, P/N 4318032, should be applied to the threads to ensure the security of the nut. Under no circumstances should the original nut be reused. The 5th gear mainshaft nut has a special adhesive patch that is effective for original installation only. If a new nut is not used, loosening of the nut will occur resulting in transmission damage.
NV4500 Manual Transmission Fifth Gear:
The mainshaft nut for the standard duty manual transmission used with 5.2L and 5.9L engine is P/N 4637802. The mainshaft nut for the heavy duty manual transmission used in the 8.0L and Cummins Diesel engine is P/N 4741553.
