GM NV4500 Transmission

Specifications

The GM NV4500 Transmission is one of the most trusted manual gearboxes for heavy-duty applications. Manufactured by New Venture Gear, it was widely used in Chevrolet and GMC 2500 and 3500 series trucks for its strength, reliability, and towing capacity.

This 5-speed manual transmission features a cast-iron case, aluminum shift cover, and a synchronized first to fifth gear (except for the early non-synchronized first). It includes a 0.73:1 overdrive, making it ideal for highway driving while still handling high torque loads. The NV4500 is compatible with both gas and diesel GM engines, making it a versatile choice for various truck builds.

At Tagore Autoparts, our used and remanufactured GM NV4500 transmissions undergo rigorous inspections, including gear integrity checks, synchronizer verification, and bearing testing. Each unit is VIN-matched to ensure precise compatibility with your GM truck.

Whether you need a replacement for towing, off-road performance, or daily driving, the GM NV4500 transmission delivers unmatched durability. Backed by warranty coverage and nationwide shipping, we ensure a reliable, cost-effective replacement solution.
