Gearstar 4R70W 4x4 Level 4 Transmission 600HP, 500 lb-ft, 2600–4500 Stall
SKU: GSTGS4R7024X4L4
4R70W Level 4 is designed for Ford Small Block engines using a 2-bolt starter & 4x4 applications with a factory transfer case. **It 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 4R70Ws are designed to work with 1998-2003 wiring for standalone transmission controllers.
