Tech Note 1: Conversion
QU10191 and QU10205 are for 1992-1998 GM NV4500 transmissions without synchronized reverse gear. Unlike QU10710 and QU10204, QU10191 and QU10205 do not have the tapered seat for the reverse gear synchronizer ring. If you would like to convert your 1992-1998 GM to have a synchronized reverse gear, see Tech Note 2 (1992-1996) or Tech Note 3 (1997-1998).

Tech Note 6: 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.
