QU10107 Early NV4500 Shift Finger Plunger Spring

QU10107 Early NV4500 Shift Finger Plunger Spring is used on 1-2 and 5-R shift lugs to put tension against the shift lever stub. These springs are only found in the early shift covers that had the integral shift tower (1992-1994 GM and 1992-1997 Dodge). Not a common part requiring replacement, but if your shift lever feels "sloppy" in neutral, weak plunger springs are the likely culprits. USA Made.

Tech Note 1: Product Note
Two QU10107 Springs were used in early NV4500 Shift Covers. There is one in the reverse fork and one in the shift lug on the 1-2 shift rail.

Tech Note 2: 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 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 V1003DVD NV4500 Overhaul Video for more information.
