Tech Note 1: Losing 5th Gear
Of all the NV4500 variants, The GM 4x2 version of the New Venture NV4500 5 speed manual transmission is the most resistant to "losing fifth gear".
Tech Note 2: Mainshaft Specs
QU10212 is a 4x2 35 spline mainshaft. The original application for QU10212 was 1992-2002 GM C3500HD 4x2 cab and chassis trucks with 15,000 GVW. Large numbers of these transmissions were built after 2002 and released to the aftermarket for conversion applications. There was also a nearly identical transmission that I was told was built for export which used QU10213 Mainshaft. QU10213 takes a bit larger inside diameter 5th gear, speedo spacer, and mainshaft spacer.
