Notes
- 4R70W Level 4 designed for Ford Modular engines using a 3-bolt starter & 4x4 applications with factory transfer case **will not fit the early 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 controllers.
