50-6902 : GM 700R4 to GM NP205 Adapter Kit (replacing TH400)

Advance Adapter
The GM 700R4 main shaft kit is used when replacing a TH400 in model years 1971-84. Once installed into the 700R4, the output side of the 700R4 looks identical to a 4WD TH400 that is being replaced. The adapter kit includes a new output shaft, plastic washer, adapter plate, TH400 gasket, o-ring, metric fastening hardware, and adapter instructions.
Transfer Case
The adapter assembly fits 1971-84 GM NP205, 1971-79 NP203 transfer cases that were previously used with a TH400.This adapter assembly requires that use of the original GM TH400 4wd adapter.
This kit is designed for exclusive use with the 700R-4 / 4L60 / 4L60E. The overall case length of the transmission is 23.375”, has non-removable bell housing, and a 4 bolt square rear case. Late model 4L60E automatics will have removable bell housing and a 6 bolt hex pattern rear case.
Note: The late model 4L60E automatics will require VSS kit. We manufacture two styles of VSS kit's, 716073 fit model years 1993-96 and 50-0405 fit model years 1997 to current.
