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 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.

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.

Love and amazing for the price!
Color: White, Style: Wall Cabinet, Color: White, Style: Wall Cabinet
Perfect! I'm a renter and didn't want to spend an arm and a leg on something that might not work in the next place so this looked like it would be a good fit. I really wasn't expecting much for the price point but I was VERY pleasantly surprised. It's a great piece. I love assembling things (I'm an Ikea pro) but this had literally the easiest and most explicit instructions I have ever seen. Every piece is clearly labeled. The hardware comes in a bubble pack, again clearly labeled. Rhe instructions are very clear. Another thing I appreciated was the mounting mechanism which is a French cleat. It is much easier to level and screw in a cleat than to recruit help and try to hold a cabinet in place and try screwing it in. I'm a fat middle age woman and I had no problem mounting it by myself. Notice there are no screws visible on the outside. That was a huge selling point for me. Only con is that for the quality of everything else, the shelves are on the thin side, placing anything substantial would definitely make them bow. Background is a scrap of peel-and-stick.

Good cabinet choice
Color: White, Style: Wall Cabinet
I needed a wall cabinet for a recessed area above the toilet. This one fits the area perfectly and provides a good amount of storage in an otherwise wasted space. It looks good as it coordinates well with my white shaker style cabinets elsewhere in the room. It was easy to assemble, doors lined up perfectly, and mounting was a breeze with the included screws and hardware. It doesn't get hard use in this location, but seems sturdy after almost a year.
