ATS 309-964-3104 E4OD STG 6 PACKAGE FOR 89-91 FORD F250/F350 4X4 WITH DIESEL

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 E4OD Features:

• ATS Five Star Torque Converter featuring a billet cover, five lock-up clutches, available in either low or high stall configurations
• ATS billet input shaft
• ATS Commander Lock-Up Controller
• ATS billet flex plate
• ATS billet intermediate shaft
• ATS billet output shaft
• High performance overdrive, intermediate and forward clutch packs, with one additional clutch added per section
• Modified transmission pump to increase line pressure, which provides increased clamping force on the clutch packs
• Modified valve body that focuses around precise shifts, increase line pressure and increasing the torque capacity of the E4OD
• New bearings, seals and gaskets
• New low roller clutch, heavy duty intermediate sprag, bonded coast and overdrive pistons
• ATS Deep Transmission Pan which adds 5 quarts of fluid over stock, which helps keep the transmission cool

The Stage 6 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 6 setup. This allows the user to base lock-up on vehicle speed and 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 and where power at low rpm 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 6 features the addition of a billet flex plate and intermediate and output shaft. 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.

We also add a billet intermediate and output shaft to the Stage 6 package. This is a requirement for trucks with aftermarket injectors, injection pump and turbo. During high torque situations (i.e. racing), our billet intermediate shaft will absorb the torsional loads to transfer power through the transmission. Without a billet intermediate and output shaft, the transmission is at risk for failure during heavy towing/competition use.

The ATS Stage 6 Package is designed as the end-all of E4OD. The transmission package comes with a 5 year / 500,000 mile warranty.

The ATS 309-964-3104 E4OD Stage 6 Package for 4WD 1989-1991 Ford Diesel trucks is the ultimate transmission upgrade for those seeking increased reliability, performance, and towing capabilities. Engineered specifically for the E4OD transmission behind diesel engines, this package is designed to handle increased power levels with ease.

Featuring top-of-the-line components from ATS, the Stage 6 Package includes a Five Star Torque Converter with advanced lock-up clutches, a billet input shaft for enhanced reliability under heavy loads, a Commander Lock-Up Controller for precise shifting, and a billet flex plate and shafts for increased durability. The package also includes upgraded clutch packs, a modified transmission pump and valve body for improved performance, and high-quality bearings, seals, and gaskets for longevity.

One standout feature of the Stage 6 Package is the lock-up controller, which optimizes torque converter lock-up based on vehicle speed and gear selection. This results in benefits such as improved fuel economy, lower transmission temperatures, and enhanced power delivery, especially at lower speeds. Additionally, the controller can be synchronized with an exhaust brake for increased braking force during deceleration.

The billet input shaft, flex plate, and shafts included in the package are crucial for high horsepower and torque applications, ensuring reliable power transfer from the engine to the transmission. With these components in place, the Stage 6 Package is ideal for trucks with aftermarket upgrades such as injectors, injection pumps, and turbos, providing peace of mind during heavy towing and competitive use.

Backed by a 5 year / 500,000-mile warranty, the ATS Stage 6 Package offers unmatched performance and reliability for Ford Diesel owners looking to upgrade their E4OD transmission.
