Specifications of an NV3500 Transmission
The NV3500 is a five-speed manual transmission found in General Motors and Chrysler trucks.
The manufacturer, New Venture Gear, is a company that was formed through the merger of the manual transmission engineering and manufacturing divisions of GM and Chrysler.
Design
The NV3500 is a fully synchronized, constant mesh transmission. The clutch housing, or bell housing, is an integral component to the transmission and is not meant to be removed. According to DodgeRam.org, the NV3500 "has a single shaft shift mechanism with all three shift forks mounted on the shaft."
Variations
The HM290 model, found in GM trucks beginning in 1988, was the forerunner of the NV3500-series transmission. This unit, and the 560 which superseded it, have four shift rails. When this transmission was re-engineered as the NV3500, a single shift rail was used in the design.
There are many design variations of the NV3500, each with unique parts. Two-wheel drive and four-wheel drive variants are available. Another variant is the NV3500HD.
Model Lines
The NV3500 transmission was deployed in the full-size half-ton Chevrolet Silverado and GMC Sierra pickups, Chevrolet S10 and GMC S15 trucks beginning in 1990, and some Dodge Dakota trucks beginning in the 1994 model year.
In the Dakota, the NV3500 is used with V-8 engines including the 3.9-liter and 5.2-liter Dodge powerplants.
Hauling Capacity
According to DodgeRam.org, the NV3500 is rated to a maximum GVWR of 7,200 lbs. and a maximum GCVWR of 11,000 lbs. The NV4500 transmission, built for larger engines, is a heavy-duty transmission for trucks that require greater hauling and towing capabilities.
