NV-4500 Transmission Variations

The New Venture 4500 (NV-4500) Manual Transmission has two different variations.  The New Venture 4500 (NV4500) is found in GMC & Dodge trucks. The bell-housing pattern for 1993-1994 GM versions is unique from the later (1995-) GM and Dodge units. The 1993 and 1994 Chevy versions have a lower first gear of 6.34:1 and an unsynchronized reverse gear. Transmissions after this period have a higher 5.61 low ratio and reverse gear synchronization.

Input shafts for the GM and Dodge units have 10 splines with 1-1/8″ diameter. GM shafts stick out their usual 6-5/8″ while the Dodge units are 7-5/8″ long.
