Tech Note 1: Kit Components
QA1028 9 Piece Synchro Ring Kit is for 1992-1998 GM New Venture NV4500 5 speed manual transmissions with a unsynchronized reverse gear. All Other NV4500 transmissions have an synchronized reverse gear and use 10 piece Kit QA1011. QA1028 includes these 9 original equipment type NV4500 Synchro Rings:
(2) QU10004 3-4 Rings
(2) QU10002 1-2 Center Friction Rings
(1) QU10003 5th Gear Ring
(2) QU10014 Inner 1-2 Steel Rings
(2) QU10015 Outer 1-2 Steel Rings

Tech Note 2: Shifting Should Be Smooth
Typically, NV4500 transmissions with stock type synchronizer rings are easy to shift, with a smooth positive feel. This is largely due to the advanced carbon fiber coatings on the rings and the use of compatible lubricants like Castrol Syntorq LT® or QU90020 NV4500 Manual Transmission 75w85w GL-4 synthetic gear lubricants. If you are experiencing shift difficulties with your NV4500, the most likely causes are: wrong or dirty lubricant, clutch issues, excessive mainshaft bearing end-play, or aftermarket brass synchro rings were installed when the transmission was rebuilt. Sometimes, changing the oil will help, but typically, by the time you get around to fixing the problem, the damage is already done.

Tech Note 3: Reusing 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: Soak Synchro Rings
Soak your synchronizer rings in QU90020 75w85w GL-4 Synthetic Manual Transmission Fluid for New Venture NV4500 transmissions. For more information on rebuilding your NV4500 transmission, order my 116 page, full color illustrated TM1003 NV4500 Rebuild Manual.

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.
