Show original supplier description
The New Venture Gear NV5600 main transmission case, also identified by part numbers 22725 and 5003578AA, is designed as a direct replacement for Dodge Ram 2500 and 3500 models equipped with the NV5600 transmission. This case is compatible with vehicles from the 1999 through 2005 model years. It is important to note that this transmission case does not fit all 2005 Dodge Ram models, as some were equipped with the G56 transmission. This distinction is crucial for ensuring proper fitment and avoiding installation issues. The part replaces Mopar part number 5003578AA and is also known by interchange numbers ZMNV22725 and AM521760A.
