Tech Note 1: Inner/Outer Steel Synchro Rings
The New Venture NV4500 5 speed transmission uses a triple cone synchronizer design for 1st and 2nd gears. It is advisable, but not required you replace QU10014 Inner Steel Rings and QU10015 Outer Steel Rings at the same time you replace QU10002 Center Friction Rings. To reuse QU10014 and QU10015 Rings, the condition of the friction surfaces on those rings must be good. If the polished steel finish is pitted, scored, or heat discolored (bluish color), you should replace them.

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 V1003DVD NV4500 Overhaul Video for more information.
