4R70W Level 4 designed for Ford Small Block engines using a 2-bolt starter & 4x4 applications with factory Ford Bronco Dana 20 transfer case. This will require the use of a standalone transmission controller unless this is going into a factory application. Our 4R70W's are designed to work with 1998-2003 wiring for standalone transmission controller. For your next project—perhaps dropping a 4.6L into a street-driven Mustang, you'll want to transition away from 4WD setups and look at a

- This transmission assembly is 26-1/2" overall in length is 1.750" longer than the early Bronco drivetrain assemblies.
- The original V8 drivetrain assembly is normally 24.750"" and there will only be approximately
- 1-3/4" of a difference. The U-shaped shifter pattern used on the later model Bronco transfer cases may not
- be compatible with this adapter housing. You will need to either modify the mounting or change to the earlier
- model shifter pattern that had a straight design. This requires new shift rails to be install in the transfer case.
- 2. The crossmember support that we have provided on the bottom of the new adapter housing is very similar
- to the original support bracket. It may be necessary to modify the donuts and bolts in order to assemble the
- existing crossmember to the new adapter housing.
- This kit has been designed to retain the stock Bronco rubber T/C mounts. These mounts were previously
- equipped with a 1/2" bolt. Our casting has been drilled and tapped for a 7/16" bolt. We have supplied this kit
- with the necessary sleeves, washers, and bolts to properly secure this adapter.
