Applications

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: Common Failures
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 misalignment (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..
