Built To Keep Your 68RFE Alive And Working Hard

If your stock 68RFE has been giving you reasons to worry, the ATS Stage 1 Transmission Package brings the kind of reassurance every 2007.5-2011 RAM Cummins owner wants before hitting the road. This setup tackles all the weak points that tend to show up once you add power, tow heavy, or simply rack up miles, giving you a transmission that feels far more confident than the factory ever intended. The upgraded clutch packs with larger surface areas help the truck hold power without slipping, which is something you will notice the first time you roll into the throttle. ATS also improves shift quality by pairing the transmission with their Co-Pilot controller, which automatically adjusts line pressure to match driving conditions. What this means in real life is smoother low-load shifts and much firmer, safer engagement when the truck is working hard. The deep pan and reinforced internal components help control heat, which is one of the biggest enemies of the 68RFE. With all of these upgrades working together, you get a transmission that finally feels like it belongs behind a 6.7L Cummins, especially if you depend on your truck for towing or long hauls.

Inside The Engineering Behind A Stronger More Responsive 68RFE

The Stage 1 build focuses heavily on correcting the internal weaknesses of the early 68RFE, starting with the clutch packs and hydraulic circuits that handle the bulk of the work. The forward, overdrive, 2C, and 4C clutches all receive increases in surface area, which gives the transmission more holding power without requiring additional space inside the case. Along with that, ATS replaces the fragile factory sprag with a stronger roller clutch design that improves durability and lubrication under load. The valve body is also completely reworked, using a billet channel plate that eliminates the warping and cross-leaks common to the thin stock casting. This upgrade alone improves shift consistency and reduces the lag you might feel in gear changes. The pump assembly receives a redesigned regulator valve and updated hydraulic control to allow a wider, smarter range of line pressure. Every seal, gasket, and internal component is replaced during assembly, bringing the whole system back to a reliable baseline. With the Co-Pilot controller tying it all together, the transmission responds more precisely to boost, throttle input, and towing demand, creating a stronger and more predictable driving experience.
