Tech Note 1: Loss of 5th Gear
The infamous "NV4500 5th Gear Failure" is almost always wrongly blamed on the nut. Having your nut back off is a consequence of an inadequately supported mainshaft 5th gear on stock and full spline mainshafts. Radial and axial movement of the gear will loosen the nut. No nut design will prevent 5th gear failures, although they may delay them. The only way to solve the problem is to redesign the shaft, gear, and nut set which we did with our Torque King® mainshaft sets. See Tech Article 5th Gear Failures and Solutions for more information.

Tech Note 4: 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.
