Advance Adapters Bellhousing Kit For Dodge Heavy-Duty, 1-1/4th 10 Spline Input Shaft 2WD NV4500 Transmission Assembly
We offer a complete adapter package for this transmission swap. The components in this packages that we do offer can also be purchased separately. This package is only compatible with the Dodge Heavy-Duty 2WD NV4500 transmission. This transmission can be ordered from a transmission repair shop or a Dodge dealership.
NOTE: the 1998 and newer transmissions do not offer any type of speedometer provisions. When obtaining your transmission, we recommend that a 1997 and earlier transmission be obtained. The handle assembly in this kit fits the 1998 and earlier transmission handle configuration. If you have decided to use a later model transmission without a speedometer drive, then you will need to substitute 716050D with 716050D1.
The speedometer components of the Getrag transmission will directly interchange into the new Dodge Heavy Duty 2WD transmission. On most speedometer housings, you'll find an "L" fitting which reversed the speedmeter cable coming out of the Getrag transmission. When installing the speedometer housing onto the NV4500 transmission, you will need to remove this fitting to obtain the proper speedometer rotation.
The output shaft on this transmission has 31 splines. We have included a new output shaft yoke in this kit, 716087. Driveline modifications will be required (shorten approximately 6 inches). Floorboard modifications are required, since the NV4500 shift handler location set further back that the Getrag.
Since the crossmember mounting lacation on the Getrag is different then on the NV4500, your stock crossmember will need to be modified. The front side of the stock Getrag crossmember will need to be modified to clear the NV4500 tailhousing. By modifying the stock crossmember and using a stock Chevy Turbo 350/400 automatic rubber support, you can retain your crossmember in the stock location. The Chevy mount sets into the Dodge crossmember channel. You will also need to drill two holes in the Dodge crossmember for the bolts to fir the Chevy rubber mount.
