ATS Built 4R100 Transmission Package

Upgrade the factory transmission in your 1999-2003 Ford 7.3L Powerstroke with the ATS Built 4R100 Transmission. Innovation and technology set ATS apart from the rest. Between their engineering team, and their transmission specialists, ATS has logged thousands of hours in building, testing, and manufacturing to bring you the best transmission worth of bolting up behind your legendary Powerstroke engine. ATS transmissions include extensive modifications so you can put power to the ground whether you're towing, daily driving, or on the race track. By increasing line pressure, clutch pack surface area, and modifying the valve body, the ATS 4R100 becomes a consistent, responsive, and dependable transmission. 

The ATS Stage 1 4R100 is designed for trucks that see daily driving and towing duties, as well as minor modifications like an upgraded air intake, exhaust or mild tune.

The Stage 2 adds a billet 300M input shaft. As power increases over 400hp, or considerable weight will be towed, the input shaft takes the brunt of it. The ATS input shaft is designed to withstand extreme torque, converter lock-up sooner than stock, and competition and towing use. The ATS Stage 2 4R100 is designed for trucks that see daily driving and towing duties, aggressive tuning, and a modified turbo and/or injectors.

The Stage 3 includes a billet 300M input shaft. As power increases over 400hp, or considerable weight will be towed, the input shaft takes the brunt of it. The ATS input shaft is designed to withstand extreme torque, converter lock-up sooner than stock, and competition and towing use. Beginning on the Stage 3, ATS includes a Co-Pilot Transmission Lock-up Controller. This controller allows the user to lock the converter based on vehicle speed. The result is more power to the ground at a lower speed, thus improving acceleration, lowering transmission temperatures and helping fuel economy. The Co-Pilot will also synchronize torque converter lock-up with an exhaust brake, for added braking force. The ATS Stage 3 4R100 is designed for trucks that see daily driving and heavy towing duties, aggressive tuning, and a modified turbo and/or injectors.

The Stage 4 includes a billet 300M input shaft. As power increases over 400hp, or considerable weight will be towed, the input shaft takes the brunt of it. The ATS input shaft is designed to withstand extreme torque, converter lock-up sooner than stock, and competition and towing use. The Stage 4 package includes a Co-Pilot Transmission Lock-up Controller. This controller allows the user to lock the converter based on vehicle speed. The result is more power to the ground at a lower speed, thus improving acceleration, lowering transmission temperatures and helping fuel economy. The Co-Pilot will also synchronize torque converter lock-up with an exhaust brake, for added braking force. The Stage 4 package adds a billet flex plate. The flex plate becomes important in high horsepower/torque applications, during competition use, or when towing heavy loads. By increasing the reliability of the flex plate, we can ensure a solid transfer of power from the motor to the transmission. The ATS Stage 4 4R100 is designed for trucks that see daily driving and heavy towing duties, aggressive tuning, competition use and a modified turbo and/or injectors.

By increasing the reliability of the flex plate, we can ensure a solid transfer of power from the motor to the transmission.For competition and extreme towing, we add a billet intermediate shaft to the Stage 5 package. By absorbing and transferring extreme power and load, the billet shaft can increase reliability in the 4R100 platform. The ATS Stage 5 4R100 is designed for trucks that see daily driving and extreme towing duties, aggressive tuning, competition use and a modified turbo and/or injectors.

For competition and extreme towing, ATS add a billet intermediate and output shaft to the Stage 6 Package. By absorbing and transferring extreme power and load, the billet shafts increase reliability in the 4R100 platform. The result is a transmission built for drag racing, sled pulling, dyno competitions or towing extreme loads. The ATS Stage 6 4R100 is designed for trucks that see daily driving and extreme towing duties, aggressive tuning, competition use and a modified turbo and injectors.
