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. Ensure that the power of your Powerstroke is getting to the ground with an ATS Transmission Package.

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 6 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, ATS adds a billet intermediate and output shaft to the Stage 6 package. By absorbing and transferring extreme power and load, the billet shaft can 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.

SHIPPING POLICY - Due to the size and weight of transmissions, they cannot be shipped through traditional couriers, such as UPS, FedEx, USPS, etc. and MUST be shipped via truck freight. We do not offer free shipping on transmissions, however, we do offer a very competitive rate charged at checkout checkout. Once your core transmission is ready for pick up, you just need to give us a call or send us an e-mail with your original order number and the core tag on the transmission, and we can supply you with a quote on the return shipping as that is not covered in the original shipping cost. Otherwise, we give you the option to coordinate the return shipping on your own and independently pay your courier of choice. As always, if you have any questions, give us a call or send us an e-mail.

Wonderful Room Partition !
Color: Black, Size: 88"- 4 Panel
This product is made very well, packaged, and assembled with no problems. All parts and tools are included (except a Phillips screwdriver.) I put this item all together by myself on a bed to make it easy and simple. I made sure that every screw head was attached where the recessed dimples are located on the vertical poles, just don't overtighten anything. Everything fits like a charm, good quality, looks great, perfect height, rolls with ease, proper privacy, really impressive ! I got the 4-panel in black color. I would certainly buy this item again ! Thank you !

Sturdy and Easy to Move
Color: Black, Size: 132"- 6 Panel
This 6 ft black partition on wheels is exactly what I needed to divide space without sacrificing style or stability. It’s sleek, professional-looking, and blends in well with any environment—from office spaces to home studios. The build quality is impressive—very sturdy and doesn’t wobble at all once it’s in place. The wheels glide smoothly and lock securely, making it easy to reposition or keep stationary as needed. Assembly was quick and straightforward, with all parts clearly labeled. Overall, this partition is a perfect combination of functionality and design. Highly recommend it if you need a durable, mobile room divider that looks great and performs even better.
