Advanced Adapters 1989-1993 Dodge Heavy Duty NV4500 Manual Transmission Adapter Kit – 712584

$620.00

Product Highlights:

Between the years of 1989 to 1993, Dodge used a German made Getrag 5 speed transmission coupled to the Cummins diesel engine. These transmissions were used in both 2WD and 4WD vehicles. The availability of re-manufactured transmissions and replacement parts have been extremely difficult to locate. We have developed a bellhousing that will permit the use of the newer Heavy-Duty NV4500 transmission.Many customers are aware that the NV4500 is currently coupled to the Cummins diesel. The logical reasoning might be to simply use a stock NV bellhousing from Chrysler. Although this may be true, as was our initial thought, these original Chrysler components for the NV4500 transmission proved to be extremely expensive. Not only would you need a new bellhousing, but you will also require new clutch components, a slave cylinder, and considerable labor.

The bellhousing we manufacture bolts to the Cummins 5.9 diesel and utilizes the stock slave cylinder, clutch arm, and release bearing. This bellhousing comes with a new pilot bushing for both the 2WD and 4WD applications. The 4WD kits also include a crossmember mount and transfer case shifter bracket.

TRANSMISSION MODIFICATIONS for 2WD and 4WD VEHICLES:
Prior to assembly, modification will be required to the front portion of the NV4500 transmission. The bearing retainer must be removed from the front of the 5 speed and shortened to a length that is 4.297″ long. This can be done by using a cut off wheel or engine lathe. By shortening the bearing retainer, this will prevent any interference with the hub on the clutch disc. The bellhousing should be test fitted up to the back of the Cummins block to check flywheel and clutch assembly clearance on the inside of the our bellhousing.

Floorboard modifications for the shifter lever will be required. Since there is a 4-1/2” difference in length between the Getrag and the NV4500, the hole in your floorboard will need to be located back roughly 4-1/2″ for the handle location.

The Advance Adapters bell housing is designed to adapt any year Dodge Heavy Duty NV4500 to the Cummins Getrag adapter plate. Our bellhousing will retain the use of the Getrag slave cylinder, clutch arm, and release bearing.
The bellhousing kit includes a 356 T-6 aluminum bellhousing, pilot bushing, transfer case shifter bracket, crossmember support, fastening hardware, and adapter instructions.
