TH400 to Standard Round 6 bolt 1-1/4" Thick Transmission Adapter Kit

This adapter is designed for the super short shaft 4wd TH400 with a stick out length of approximately 1-3/8" to mate to standard 6 Bolt Round Pattern Transfer Cases.

These include Atlas, Stak, D300, BlackBox, and planetary gear box. Along with your Ford, dodge, jeep style transfer cases.

This Style TH000 would have had a New Process 203 bolded onto it from factory.
This once forgotten version of transmission is now able to be used with many types of transfer cases.

Note:

This is not compatible with GM transfer cases. They do not have a standard 6 bolt round pattern.

You must also ensure the input shaft is correct on your transfer case.
