700R TO BRONCO DANA 20 T/C

Advance Adapter

Our GM 700R-4 adapter to the Bronco Dana 20 is 2.50″ in length. The adapter material is 356 T-6 heat treated aluminum alloy. The adapter kit includes two adapter housing, new 700R-4 output shaft, spud shaft, shifter linkage bracket, bearing retainer, bearing, snap ring, o-ring, gasket, seal, fastening hardware, and adapter instructions. The stock Bronco crossmember will need to be replaced or modified to fit this adapter kit.

Transfer Case

The adapter assembly will fit any 1966-77 Bronco Dana 20 transfer case. This adapter will only work with the “T” style shifter. Transfer cases with a “J” style linkage will require modifications to retain this linkage.

Transmission

This kit is designed for 2WD or 4WD 700R-4 / 4L60 / 4L60E manufactured thru 1996. The overall case length of the transmission is 23.375″, has a non-removable bell housing, and a 4 bolt square rear case. Late model 4L60E automatics will have a removable bell housing and a 6 bolt hex pattern rear case. The late model automatic will require an additional Advance Adapter to work with this kit.
