TRANSMISSION MODIFICATIONS REQUIRED:
Prior to assembly, modification will be required to the front portion of the new 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 hacksaw or engine lathe. By shortening the bearing retainer, this will prevent any interference with the
hub on the clutch disc. Also, fit the bellhousing up to the back of the Cummings block to check flywheel and clutch assembly
clearance on the inside of the new bellhousing. You may need to grind on the inside of the bellhousing for added clearance
on the ring gear.
When assembling the transmission to the new bellhousing, DO NOT USE the bolts to draw the bellhousing into its final
position. Make sure that the bellhousing will receive the transmission without any interference problems. This bellhousing
is only compatible with the heavy-duty Dodge NV4500 transmission. This transmission will have a 1-1/4"-10 spline clutch
disc that will be directly interchangeable with the original Getrag components.
Floorboard modifications for the shift lever will be required. There is a 4-1/2" difference between the Getrag and the NV4500
on the handle location. The hole in your floorboard will need to be located back on the floorboard roughly 4-1/2".
The original Getrag transmission used a seal on the backside of the main transmission case. They also used a seal on the front
side of the transfer case inside the adapter housing. When using the new transmission, the seal on the transmission side has
been eliminated and the only seal separating the two gear boxes is the original seal located on the front side of the transfer
case. We have had numerous customers with the NP205 transfer case use the special NV4500 transmission fluid in both
the transfer case and transmission in order to avoid any contamination between the two units. The original seal should provide
ample protection from any contamination. We do not feel that it is necessary to use one common fluid for both gear boxes.
We suggest monitoring the quality of the fluid in the transfer case in order to prevent any problems.
