Product Name ATS E4OD Stage 4 Package 1989-1991 Ford 2WD ATS Diesel Manufacturer ATS Manufacturer Part # 3099423104 Thoroughbred Diesel Part # ATS3099423104 Fitment Notes 1989-1991 Ford 2WD
The Ford E4OD transmission was designed to fit behind various powerplants including gas and diesel engines. Most failures revolve around the torque of the diesel motor, especially when power is increased over stock. The good news is that the framework of the E4OD allows for substantial increases in reliability and capability. ATS E4ODs
ATS Deep Transmission Pan which adds 5 quarts of fluid over stock, which helps keep the transmission cool
The Stage 4 package includes a billet input shaft for increased reliability when towing heavy loads, under modified power levels or street performance. The billet input shaft is designed to withstand greater torsional loads than the factory shaft, thus increasing reliability.
The shaft is made of billet 300M material and precisely machined for an exact fit. In addition, we add a lock-up controller for the torque converter on the Stage 4 setup. This allows the user to base lock-up on vehicle speed in any forward gear. This provides several benefits, including increased fuel economy, lower transmission operating temperatures and more power to the ground, at a lower speed. This feature becomes useful in towing situations and performance applications where power at low rpms is desired. For those trucks with an exhaust brake, the controller will synchronize torque converter lock-up with the brake.
This will allow the converter to stay locked on deceleration to increase braking force. The Stage 4 features the addition of a billet flex plate. The billet flex plate is designed for high horsepower/torque trucks and those that tow heavy. The flex plate is the first point of power transfer from the motor to the transmission assembly. By using a billet steel flex plate, we can increase the reliability of power transfer from the crank to the converter.
The ATS Stage 4 Package is designed for trucks that are used for light/moderate/heavy towing, greater-than-stock power levels and racing/street performance.
