NOTE:
1. This adapter is designed for exclusive use of the Dodge 4WD 23 spline output version of the NV Model 4500
transmission. You must use this transmission due to the length and spline size of the output shaft. The shaft must
be shortened to the 5.420" cutoff length (see Page 3). In order to cut the shaft off, you will need to remove the
tailhousing. The shaft can be cutoff using and abrasive cutoff saw or a skill saw equipped with a special metal cutting
blade. Be sure to use safety glasses during this procedure.
2. The assembly of the adapter plate to the transfer case should be very much like the originally transmission that is being
replaced. A new flat washer and nut are provided for the early model vehicles to hold the two gears in position.
3. The alignment between the new adapter plate and transfer case must be performed by the new bearing that has been
included with the adapter. This sealed bearing will have the external snap ring on the outside of the adapter similar
to the original transmission. This will prevent the special transmission fluid of the New Venture gear box from mixing
with the transfer case fluids. When installing the adapter to the NV4500 make sure the stock dowel pins are
in the transmission.
4. When using this transmission assembly with a 6 cylinder Toyota engine, you may need to modify the gas tank area
on 1979 and newer vehicles. It would be advisable that your vehicle be equipped with a suspension lift and you should
plan on removal of the stock rear crossmember. A new Advance Adapter crossmember #716022, will be required.
This transmission assembly is the very shortest possible and careful planning is a must when performing the
installation with the stock 6 cylinder.
5. The transfer case shift controls will need to be modified for use with the new transmission. A new bracket #715532
has been supplied.
