The GM 6L80E/6L90E 6-speed is one of the most-searched used transmissions nationwide. We pressure- and shift-test each unit and VIN-match it (it does NOT interchange with the lighter 6L45/6L50). 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 6L80E / 6L90E
The 6L80E/6L90E commonly fails at the valve body (dirty solenoids and worn bores cause harsh or slipping shifts) and shows wave-plate wear along with 1-2-3-4 and 3-5-reverse clutch wear. We pressure- and shift-test every unit, inspect the valve body and clutch packs, and VIN-match it — the heavier 6L90E and lighter 6L80E do NOT interchange with the 6L45/6L50. Plan on a TCM adaptive relearn after install to reset shift pressures.
Used vs. remanufactured 6L80E / 6L90E — which to buy
A tested used 6L80E is a strong value when the valve body and clutches check out, and ours are pressure- and shift-tested first. Remanufactured is the safer play on a tow rig or high-mileage truck where you want the valve body and wave plate refreshed with a longer warranty. We carry both and VIN-match 6L80E vs 6L90E to your vehicle. Send your VIN for honest used-vs-reman pricing.
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
