The NV4500 was the initial manual transmission of choice for the 2nd Generation Cummins that Ram continued to use through 2004 before being replaced by the 6 speed NV5600. The NV45 is widely popular in many applications due to its relative strength and parts availability. Really, this 5 speed's only faults were the original 12.25streetability" out of this bad boy.
The 1200 Series is a larger diameter assembly, which is designed for high torque output applications. This delivers a higher holding capacity, making it an ideal candidate for heavy towing applications. The 1200 Series Twin Disc features one sprung disc, creating a slightly smoother engagement compared to two rigid discs.
