ATS Diesel 2012+ Dodge 68RFE Performance Valve Body (For Use With Gray Connector Solenoid Pack)
This is the ATS Diesel 68RFE Performance Valve Body, part number 303-900-2380, built for 2012-2018 Ram 2500, 3500, 4500 and 5500 trucks running the 6.7L Cummins. It is the valve body casting only, with no solenoid pack included, so it is meant to bolt in behind the gray-connector solenoid pack that these trucks already carry rather than replace it.
The 68RFE is a clutch-to-clutch automatic with no mechanical backup, meaning every gear change depends on the valve body steering line pressure through its bores to the right clutch pack the instant the solenoid pack commands it. ATS reworks the casting with upgraded accumulator seals and a stronger accumulator plate so the hardware can physically survive higher line pressure than a factory unit without the accumulators blowing apart, and it opens up oil feed to the clutch packs that take the most abuse under load. By ATS's own figures, the valve body on its own, running against the stock TCM, is good for roughly 100 extra horsepower on an otherwise healthy transmission. The fuller gain of around 200 horsepower over stock only arrives once the valve body is paired with ATS's separate Co-Pilot controller, since the stock computer will not command more line pressure than it is programmed for.
This valve body is a preventive upgrade for a transmission that is still shifting correctly, not a fix for one that is already flaring, slipping or storing codes on an unmodified truck. If your 68RFE has a complaint right now, work through our 68RFE valve body problems and testing guide first so you are not masking a hydraulic fault with a performance part. Confirm your truck falls in the 2012-2018 window this specific part number is cut for; ATS sells separate valve bodies for the earlier gray/white-connector trucks and for the 2019-and-up redesign, and none of the three interchange.
Built for 2012-2018 Ram 2500/3500/4500/5500 trucks with the 6.7L Cummins and the gray-connector solenoid pack already in the transmission. Because the solenoid pack is sold separately, verify the connector color on your truck before ordering - if you are not sure which pack you have, our 68RFE solenoid kit listing covers the matching pack. The full 68RFE parts collection lists every other part sold for this transmission, including the paired controller for the larger power gain.
Drain the fluid, drop the pan, unplug the solenoid pack wiring harness and swap in the new valve body, then refill with Mopar ATF+4 only and run the TCM's drive-learn relearn procedure instead of driving normally, since the computer needs to relearn clutch apply timing against the reworked casting. Because towing and tuned use are exactly what this part targets, and the failures it is built to prevent are heat-driven as much as pressure-driven, consider a 68RFE pump and a fresh 68RFE overhaul kit at the same time if the transmission has meaningful mileage on the original clutches.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. Part 303-900-2380 is the valve body casting only. It is built to bolt in behind the gray-connector solenoid pack these trucks already carry. If your pack needs replacing, order it separately.
By ATS's own figures, roughly 100 extra horsepower on a stock, healthy transmission with the factory TCM. Reaching the fuller gain of around 200 horsepower over stock requires pairing it with ATS's separate Co-Pilot controller, since the stock computer will not command higher line pressure on its own.
Not necessarily. This is a preventive and performance upgrade for a transmission that still shifts correctly, not a repair for one already flaring, slipping or throwing codes. Diagnose an existing complaint before assuming this part will correct it.
2012-2018 Ram 2500, 3500, 4500 and 5500 trucks with the 6.7L Cummins and the gray-connector solenoid pack. ATS sells separate, non-interchangeable valve bodies for earlier trucks and for the 2019-and-up redesign.
Mopar ATF+4 only. Refill with ATF+4 after the swap and run the TCM's drive-learn relearn procedure rather than driving normally, since it needs to relearn clutch apply timing against the reworked valve body.
Worth considering. Since this part targets towing and tuned applications where clutch wear accelerates faster, a fresh overhaul kit and a known-good pump are good insurance if the transmission already has meaningful mileage on the original clutches.
