About this product
The Ford E4OD transmission was designed to fit behind various powerplants including gas and diesel engines. Most stock failures revolve around the intense torque of diesel motors, especially when power is increased over stock. Fortunately, the robust framework of the E4OD allows for substantial increases in reliability and capability when upgraded with engineered high-performance components.
ATS Diesel E4OD Performance Transmission Packages re-engineer the weak links to deliver bulletproof power transfer, whether you use your truck for light daily driving, heavy towing, or high-horsepower competition.
