ATS Diesel 2007+ Dodge 68RFE Performance Valve Body
This is the standalone ATS Diesel performance valve body, part number 303-900-2326, built for 2007.5-2011 Ram 2500/3500 trucks running the 6.7L Cummins and 68RFE. It is the hydraulic half of ATS's 68RFE upgrade path on its own, without the Co-Pilot controller, for a truck owner who wants the reworked valve body's added holding capacity but is not adding ATS's separate pressure-control module.
The 68RFE is a clutch-to-clutch six-speed with no mechanical fail-safe, so the valve body's job is converting the TCM's electrical shift commands into hydraulic action, routing line pressure through its bores and spool valves to the correct clutch pack at the right moment. ATS reworks that casting with redesigned accumulator piston seals and a higher-grade accumulator plate, and ports extra oil to the clutch packs that need more pressure under load, so the hardware can physically carry more line pressure than the stock casting without the accumulators blowing out. On a stock transmission that still has the factory TCM commanding stock pressure, ATS's own figures put the gain from the valve body alone at roughly 100 horsepower and up; reaching the fuller gain of around 200 horsepower over stock requires adding the separate Co-Pilot controller later, since the valve body cannot command higher pressure by itself.
This is a preventive and performance upgrade for a transmission that is still working correctly, not a repair for one that is already flaring, slipping or throwing codes on a stock, unmodified truck - diagnose an existing complaint first with our 68RFE valve body problems and testing guide before assuming a performance valve body will fix it. Confirm you are running the 2007.5-2011 trucks this specific part number is built for; ATS sells a separate valve body for 2012-2018 trucks that is not interchangeable with this one.
Built for 2007.5-2011 Ram 2500/3500 trucks with the 6.7L Cummins and 68RFE. This valve body requires the solenoid pack with the white connector already installed in your transmission - it does not include a solenoid pack or any electronics. If your truck has the earlier gray-connector solenoid pack, order a matching 68RFE solenoid kit alongside this upgrade, and confirm your connector color before you buy. See the full 68RFE parts collection for every other part sold for this transmission, including the paired valve body and controller kit for a larger power gain.
Drain the fluid, drop the pan, disconnect the solenoid wiring and swap in the valve body, then refill with Mopar ATF+4 only and run the transmission's drive-learn relearn procedure afterward rather than driving it normally, since the TCM needs to relearn clutch apply timing against the reworked hardware. Because towing and tuned applications are what this part targets, and the failure modes it prevents are heat-driven as much as pressure-driven, pair it with a heavy duty cast aluminum transmission oil pan if you are not already running improved cooling.

No. This listing is the valve body alone. ATS's own figures put the gain from the valve body by itself at roughly 100 horsepower and up on a stock transmission; reaching the full gain of around 200 horsepower over stock requires adding the separate Co-Pilot controller, since the stock TCM cannot command the higher line pressure on its own.
Not necessarily. This is a preventive and performance upgrade for a healthy, stock-shifting transmission, not a repair kit. If your truck is already flaring, slipping or throwing codes, diagnose the actual fault first rather than assuming this part will correct it.
No. This valve body requires the solenoid pack with the white connector already installed in the transmission. Confirm your connector color, or order a matching solenoid kit alongside this upgrade, before you install it.
This specific part number is built for 2007.5-2011 Ram 2500/3500 trucks running the 6.7L Cummins and 68RFE. ATS sells a different, non-interchangeable valve body for 2012-2018 trucks.
Mopar ATF+4 only. Refill with ATF+4 after the swap and run the transmission's drive-learn relearn procedure rather than driving it normally so the TCM relearns clutch apply timing against the reworked valve body.
It is worth considering. The failure modes this valve body is meant to prevent, like clutch slip and converter wear under towing, are heat-driven as much as pressure-driven, so a deeper, better-cooled pan pairs well with this upgrade if you have not already improved cooling.
