Ford AODE Transmission to Dana 20 Transfer Case Adapter

Adapts Early Bronco Dana 20 Transfer Case to Ford AODE, 4R70W or 4R75W

This adapter kit is engineered to mate a Ford AODE, 4R70W, or 4R75W automatic overdrive transmission to the original Dana 20 transfer case found in a 1966–77 Ford Bronco. Whether you’re converting from 2WD or 4WD, this kit is built for electronically controlled transmissions from model years 1992–2003.
