The NV4500 transmission is considered to be the toughest and most reliable 5 speed manual transmission ever built. Robust and reliable, this 5 speed transmission was supplied in pickup trucks (up to 1 Ton) and is a popular replacement in older trucks with 4 speeds. It is also a popular replacement for 5 speed transmissions used in other 1 ton trucks, such as the Ford ZF or the Getrag (as used in Dodge Diesels before Dodge went to the NV4500). It is also the most popular truck 5 speed to be used in building up extreme Jeeps, Broncos and other hard core short wheelbase off road vehicles.

The NV4500 transmission has a case length of just 12.37", making it the perfect transmission conversion for short wheel base vehicles such as Jeeps, Broncos and Toyota Land Cruisers.
NV4500's are great replacement in older trucks with 4 speeds, plus it is also a popular replacement for 5 speed transmissions used in newer trucks. If you happen to have a Dodge 3/4 or 1 ton truck with one of the weak GETRAG transmissions, then the NV4500 transmission is the answer to your problem. . The NV4500 has stronger gears, better case and improved bearings, plus it evens allows you to retain your stock clutch setup.
The NV4500 transmission can be adapted to practically any application. It’s often cheaper to swap in a NV4500 into a Jeep instead of rebuilding the problematic factory Jeep transmission. PLUS, it's an easy swap when you use a Dodge version of the NV4500 transmission, because all that’s needed is a bell housing adapter plate. Additionally, on Dana 300 applications the Dodge version is preferable because the adapter requires a Dodge output shaft, and utilizes a stock Dodge 4x4 tail housing. The stock 23-spline input gear for the Dana 300 is retained, and the tail housing bolts directly to the mounting face of the Dana 300 transfer case.
There are plenty of adapters and conversion packages packages available to install the NV4500 transmissions into virtually any vehicle.
