Tech Note 1: Tech Help
The shift cover on NV4500 transmissions was not designed to be disassembled. No factory provisions are provided for removing the 1-2 and 3-4 forks and rails. That does not mean it cannot be done. My fully illustrated, step-by-step, TM1003 NV4500 Shop Manual details proven service procedures for NV4500 shift cover disassembly and reassembly on pages 72-84.

Tech Note 2: GM Design Change
New Venture slightly redesigned the 3-4 rail and poppet for most GM NV4500 transmissions for the 2001 model year trucks. Not all transmissions got the new parts at the same time, by 2003 all the C and K series truck cover assemblies seem to have the redesigned parts which are not interchangeable with QU10230 rail and QU10186 plunger.

Tech Note 3: Sealants
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.
