Description

QK1129 1992-early 1995 NV4500 Countershaft Drive Key Kit includes the two special Woodruff Keys used on early multi-piece countershafts. Fits all 1992-1994 GM NV4500 models with the 6.34-1 1st gear ratio and Dodge 1992-1994 with 5.61:1 1st gear ratio. Some early production 1995 GM and Dodge transmissions with the 5.61-1 ratio also came with the multi-piece countershaft.

Tech Note 1: Gear Ratios
The NV4500 transmission was initially designed to allow for close, medium, and wide ratio models, plus there were plans for a NV4600 6 speed with a double overdrive. Only the wide and medium ratio 5 speed versions saw production. GM used the wide ratio version with 6.34:1 1st and reverse gear ratios in 1992 to 1994 trucks. Dodge used the medium ratio version with 5.61:1 1st and reverse gears from 1992-1996 as did GM for 1995-1996. QU10090 Countershaft is made so the two front gears can be changed to provide different gear ratios. The shaft is keyed slotted for thick drive keys (QK1129) for each gear, plus the gears themselves are designed to be a very tight interference (press) fit to the countershaft.

Tech Note 3: 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.
