Used 545RFE / 45RFE for Sale — VIN-Verified.
VIN-verified used and remanufactured transmissions for Houston drivers — tested, warrantied, and ready to ship from Pasadena. 0% restocking, ever.
Used & remanufactured 545RFE / 45RFE — VIN-verified, tested, and shipped nationwide from our Pasadena, TX facility. Fits Jeep Grand Cherokee, Ram 1500, Durango, Dakota, Dodge Ram (4.7/5.7).
The 45RFE and 5-speed 545RFE are Chrysler's RWD/4WD automatics behind the 4.7L and 5.7L V8s. We pressure- and shift-test and VIN-match each unit because solenoid pack and valve body calibrations differ by year. These are computer-controlled, so a quick-learn / TCM relearn after install is required to set proper shift and line pressure. 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 545RFE / 45RFE
The 45RFE/545RFE is known for solenoid-pack failure (harsh or missing shifts and limp mode), worn overdrive and reverse clutch packs, and valve-body wear. We pressure- and shift-test every unit and VIN-match it because solenoid-pack and valve-body calibrations differ by year and the 4-speed 45RFE vs 5-speed 545RFE are not the same. These are computer-controlled, so a quick-learn/TCM relearn after install sets proper shift and line pressure.
Used vs. remanufactured 545RFE / 45RFE — which to buy
A tested used 545RFE is a value when the solenoid pack and clutches check out, and ours are shift-tested first. Remanufactured makes sense on a high-mileage or towing truck where you want the solenoid pack and clutches refreshed with a longer warranty. We carry both and VIN-match 45RFE vs 545RFE and year. Send your VIN and we tell you honestly which fits your Grand Cherokee, Ram, or Durango.
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.
