Used & remanufactured 68RFE 6-Speed — VIN-verified, tested, and shipped nationwide from our Pasadena, TX facility. Fits Ram 2500/3500 Cummins.

The Chrysler 68RFE is the heavy-duty auto behind the 6.7 Cummins. We test and VIN-match these tow-rated units for Ram HD trucks that work and haul. Ultra Auto Parts TX is Houston's drivetrain specialist for quality used and remanufactured transmissions, based at 5041 Spencer Hwy Ste 101 in Pasadena, TX 77505. Transmissions are one of our four core specialties (alongside engines, transfer cases, and differentials), so every unit we sell is pressure-tested, shift-verified, and matched to your exact vehicle before it ships — not pulled blind from a salvage row. We stock automatic transmissions, CVTs, and select manual gearboxes for domestic and import cars, trucks, SUVs, and heavy-duty diesels. Serving Pasadena, Houston, Deer Park, Baytown, and the greater Gulf Coast, our bilingual (English/Spanish) team confirms fitment by VIN and transmission tag number, quotes honest ranges, and backs the sale with a real warranty — so you buy with confidence and avoid a second wasted install.
Known issues we check on the 68RFE 6-Speed
The 68RFE behind the 6.7 Cummins is a tow-duty unit with known weak points we inspect: the input-clutch and overdrive-clutch wear that shows as slip under load, torque-converter lockup shudder, and solenoid-pack and valve-body faults that trip limp mode. We pressure- and shift-test every unit under simulated load and VIN-match it to your Ram HD. It is TCM-controlled, so a quick-learn relearn after install is required for correct shift and line pressure.
Used vs. remanufactured 68RFE 6-Speed — which to buy
A tested used 68RFE is a value when the clutches and converter check out, and ours are load-tested first. But because these work hard behind a diesel, remanufactured with upgraded clutches and a fresh valve body plus a longer warranty is often the smarter buy for a truck that tows heavy. We carry both and VIN-match to your Ram 2500/3500. Send your VIN and we tell you honestly which fits your towing.
Why buy a quality used transmissions?
A tested used or remanufactured transmission is often the smartest money in the whole repair. A local overhaul depends entirely on one shop’s own bench and can hide the same worn hard parts, while a new OEM unit can cost thousands more. Our used units come from low-mileage donors and are bench/pressure tested; reman units are built to OEM spec with a longer warranty. You get proven hardware, VIN-matched fitment, and a warranty in writing.
Common signs you need a replacement
Signs your transmission is failing: slipping between gears or high RPM without acceleration, hard or delayed shifts, dropping into limp mode, torque converter shudder around 40–50 mph, no reverse or no forward engagement, burnt-smelling fluid, and codes like P0700, P0730, or P0740. Once these appear, replacement is usually more reliable than a patch.

- Final drive / gear ratio must match axle for correct speed and shift
- VIN + transmission tag/ID number must be cross-checked, not just year/make/model
- Post-install PCM/TCM programming or adaptive relearn often required
