INSTALLATION NOTES:
1. This adapter is designed for exclusive use of the Dodge 4WD 29 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. The stock transfer case lock nut is retained to hold the two gears in position. The stock Toyota nut is
P/N 90179-26004.
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 bearing will have the external snap ring on the outside of the adapter similar to the
original transmission. 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. 1980 to 1985
vehicles require a custom crossmember to be made for the new transmission assembly. On 1986 & newer vehicles,
the original crossmember can be modified.
5. The transfer case shift controls will need to be modified for use with the new transmission.
NOTE:
This casting is used for both the early and late Land Cruiser transfer cases. When bolting your transfer case
to the new adapter, you will find one hole on the casting that is not used. We recommend using a dab of RTV
Blue Silicone to plug this hole.
