Used 8L90 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 8L90 — VIN-verified, tested, and shipped nationwide from our Pasadena, TX facility. Fits Silverado/Sierra 1500, Tahoe, Suburban, Yukon, Escalade, Corvette.
The 8L90 is GM's 8-speed RWD automatic behind the 5.3L, 6.2L and LT-series V8s. Harsh 2-3 shifts and shudder often trace to valve body and torque-converter issues, so we pressure- and shift-test each unit and VIN-match it to your vehicle. A TCM relearn (and updated fluid) after install is expected to clear shift-quality complaints. 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 8L90
The 8L90 is a strong 8-speed but is known for harsh 2-3 shifts and torque-converter shudder that a fluid change alone often does not cure, tracing to valve-body and converter wear. We pressure- and shift-test every unit, inspect the valve body and converter, and VIN-match it, since the 8L90 calibration is application-specific. A TCM relearn and updated fluid after install are expected to clear shift-quality complaints in your truck, SUV, or Corvette.
Used vs. remanufactured 8L90 — which to buy
A tested used 8L90 is a value when the valve body and converter check out, and ours are shift-tested first. Remanufactured makes sense on a high-mileage truck where you want the converter and valve-body shudder addressed with a longer warranty. We carry both and VIN-match the application. Send your VIN and we tell you honestly which fits your Silverado, Tahoe, or Escalade.
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.
