tech note

Dan the Gear Man® Tech Note 1:
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

Dan the Gear Man® Tech Note 2:
Typically, Countershaft 5th gear tooth failures occur from one of three causes: low or improper oil, misalignment of the maishaft to countershaft, and excessive horsepower/torque (over 275hp/600 Lb-Ft of torque). Broken 5th gear teeth are almost always caused by a combination of shaft misalginment (loose bearings or defective tailhousing) and exceeding the demonstrated 600 Lb.Ft input strength limit of the NV4500.

There are claims that cryogenically treating NV4500 gears will increase gear strength as much as 30%. Unfortunately, there does not seem to be any peer-reviewed documentary evidence to support those claims. Cryogenically treating gears is primarily a cold-hardening process that changes the molecular structure of steel to decrease wear while retaining or increasing hardness. If properly done, it is probable the cryogenic treatment process does slightly increase the impact and fatigue resistance of NV4500 gears, but not enough to significantly increase the ability of an NV4500 transmission to reliably handle more than 600 Lb.-Ft. of input torque especially considering the maximum factory torque rating of the GM NV4500 transmission is only 450 Lb.-Ft..

Dan the Gear Man® Tech Note 4:
QU10007 and QU10086 have 22 teeth and 31 internal splines. They will NOT fit Dodge NV4500HD transmissions which use a 35 spline mainshaft 5th gear. For a Dodge NV4500HD 5th gear, see QU10067.
