Tech Note 1: Product Note
QU10080 is a replacement NV4500 Reverse Fork that replaces QU10718 original New Venture Fork. The wear pads are part of the Fork so you do NOT need to order the original equipment QK1094 Pad Set. QU10080 fits 1997 and prior NV4500 transmission top covers that have integral shift towers. Applications would include all 1992-1997 Dodge, all 1992-1993 GM, and those 1994-1995 GM transmissions with the integral shift tower.

Tech Note 2: To Replace
To replace the reverse shift fork, the reverse/fifth shift rail needs to be removed from the top cover. To remove the rail, you first need to remove a non-reusable plug from the rear of the cover. 1992-1995 covers require QK1106 Early Plug Kit. 1996-1997 covers need QK1107 Late Plug Kit.

Tech Note 3: Sealants
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.
