The factory Ford 4R100 suffers from weak points in the converter, clutch pack assemblies, valve body and line pressure limitations. These weaknesses arise when the motor's power is increased or in towing applications.
ATS addressed these concerns by re-designing the torque converter, transmission pump, valve body and clutch packs. The result is a solid transmission'setup to meet the demands of your Ford Super Duty.
By increasing the line pressure, clutch pack surface area and modifying the valve body, the 4R100 becomes a consistent, responsive and dependable transmission. 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. ATS transmissions are backed by a 5 year/500,000 mile warranty regardless of power level or use.
