Tech Note 1: 1992-1994 Shift Inhibitor
The 1-2 shift inhibitor springs and weights are not included with this Kit due to a very limited supply of these parts. While supplies last, you can purchase these parts separately as needed:
QU10331 Shift Inhibitor Weight (order 4 per application)
QU10332 Round Spring (1st Gear Side)
QU10333 Square Spring (2nd Gear Side)

Tech Note 2: 1992-2007 GM
1992-2007 GM 4x2 C-Truck Rear Bearing Snap Ring:
Two wheel drive Chevy and GMC C1500, C2500, C3500, and C3500HD trucks with NV4500 transmissions use a Snap Ring to retain the rear output needle bearing in the transmission tailshaft housing. We do not include these with the Small Parts Kit as supplies are limited, but you can order these QU10319 Snap Rings as needed.

Tech Note 3: 1994-1997 Dodge
1994-1997 Dodge NV4500HD 4x2 Speedo Snap Ring:
1994-1997 Dodge two wheel drive trucks with Diesel or V10 engines use a Snap ring to secure the plastic speedometer drive gear to the output shaft. We do not include these with the Small Parts Kit as supplies are limited, but you can order these QU10330 Snap Rings as needed

Tech Note 4: Reverse Shift Fork Pads
New Venture used 2 Reverse Shift Fork Pad configurations, plus Most 1995-1996 GM models have aluminum shift forks that do not use pads, (Also many aftermarket forks do not use with pads).
For Original Equipment Forks order:
QK1094 Early Reverse Shift Fork Pad Kit fits 1992-97 Dodge and 1992-98 GM. Fork tips are straight
QK1095 Late Pad Kit fits 1998-up Dodge and GM 1999-up. Fork Tips are curved

Tech Note 5: Lubricants, Sealants, Threadlockers
Early production NV4500 Transmissions used an anaerobic sealant (QU90003) to seal between the main case and input bearing retainer, top cover, and rear housing. Mid-production units used anaerobic sealant just on the input retainer and RTV for everything else. Later production transmissions used black RTV Sealant (QU90006 or QU90005) for everything. Either type of sealant works fine (except the PTO covers ALWAYS should be sealed with RTV), but I prefer RTV for all components. Regardless of which sealant you use, make sure excess sealant does not block the lube access hole at the top of input retainer pilot that fits into the transmission case. Also, the threaded holes in the main case for the four retainer bolts and 12 PTO bolts are open ended, so you must use new bolts with factory applied threadlocker or apply Threadlocker (S24200) to your existing bolts to prevent oil seepage past the bolt threads. See my TM1003 NV4500 Shop Manual or VSG1003DVD NV4500 Overhaul Video for more information.
