Ford F-350 Super Duty 7.3L Automatic Transmission 1999, Stage 5 Transmission Package by ATS Diesel Performance®. Includes: Built 4R100 Auto Trans with PTO, 5 Star Viskus Clutch Drive Torque Converter, Extra Deep Transmission Pan, Billet Input Shaft, CoPilot Torque Converter Lock-Up Controller, Billet Flex Plate, Billet Intermediate Shaft. 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 5 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 5 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.
This package is also equipped with 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.
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.
The first thing that needs to be addressed is the clutch packs. These are the connection point for a transmission when transferring power in the gears. These clutch packs have a great deal of room for improvement. When we rebuild the transmissions in-house, we replace the overdrive, intermediate, and forward clutch pack backing plates with machined plates. This allows us to install an extra clutch in each pack. This gives us more surface area to hold added power or heavier loads. Being that there is less chance for slipping the clutches when engaged, it also increases reliability.
Next, we move to the transmission pump. This serves two purposes: circulating fluid and pressurizing it. Our main goal with the pump is to increase its pressure output ability. By doing this, we can raise pressure throughout the entire transmission, which takes us to the valve body.
The valve body is known as the "control center" of the transmission. This is what mechanically controls gear up-shifts and down-shifts, converter lock up, Park/neutral/reverse/drive, and line pressure. The main thing we are after here is line pressure, which the valve body acts as control. By increasing line pressure, we have the ability to increase the clamping force that is put on the clutch packs. Holding them tighter, also drastically increase the torque capacity on the transmission.
Finally we direct our attention to the rest of the transmission. This includes replacing all bearings and seals with new parts, and replacing the bands as well. The case is cleaned and painted with a sealed enamel to keep your transmission looking good, and prevent any type of corrosion. And finally, our deep pan reinforces the case to prevent flexing or cracking.
