Tech Note 1: Product Note
QU10081 is a component part of QK1058 and QU10215 1-2 Synchronizer Assemblies for New Venture NV4500 5 speed manual transmissions which are physically interchangeable. The interlock feature, which was used on 1992-1994 GM transmissions with 6.34: 1st gear ratio, was designed to prevent high speed down shifting in 1st and 2nd gear. To accomplish this, four sliding blocks and two springs are added to the synchro hub. When the mainshaft is rotating at high speeds, centrifugal force pushes the blocks against the sliding clutch ring and locks it in place. The early synchro hubs were slotted for the four blocks, plus there was four holes in it for the spring hooks. Once the interlock feature was abandoned after 1994/1995, the synchro hub was redesigned to eliminate the hub slots and holes. If you have the early QU10215 Synchronizer with interlock, you can convert it to a non-interlock unit simply by removing the four flyweight blocks and two c-shaped springs. The sliding hub plus the synchro springs and rectangular struts are the same for all years and models.

Tech Note 2: Synchronizer Assembly
To make a complete 1-2 synchronizer assembly, order QU10081 Sleeve + QU10038 Hub + QK1100 Synchro Strut Kit. I also recommend you get QT2008 1-2 Synchro Support which will simplify assembly. 1-2 Synchro assembly procedures are covered in my TM1003 NV4500 Shop Manual or VSG1003DVD NV4500 Overhaul Video.

Tech Note 3: Synchronizer Rings
All New Venture NV4500 transmissions use three synchronizer rings for 1st gear and for 2nd gear. The inner and outer rings are made of steel, while the center ring is faced with carbon fiber on both sides.

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 VSG1003DVD NV4500 Overhaul Video for more information.
