Rebuilt 6T31 Automatic Transmission Gearbox Complete Assembly, 6-Speed Front Wheel Drive Transaxle Fit Chevrolet Cruze Buick Excelle Verano, Fully Tested Remanufactured 6T31 Transmission

   The 6T31 is a front-wheel-drive 6-speed automatic transaxle developed by General Motors, widely equipped on Chevrolet Cruze, Buick Excelle, Verano and other 1.4L/1.6L compact gasoline cars. Our remanufactured 6T31 complete transmission assembly solves common factory defects including gear slipping, harsh shifting, delayed engagement and TCM failure, a cost-effective alternative to expensive brand-new OEM gearboxes.

All our 6T31 transmissions undergo strict full remanufacturing procedures, zero hidden damage, ready for direct vehicle installation without extra modifications.

1. Complete Disassembly & Ultrasonic Deep Cleaning All internal housings, gears, shafts, valve bodies and pistons are fully taken apart, carbon sludge & metal wear debris removed via multi-stage ultrasonic cleaning to eliminate original aging contamination.
2. 100% Replacement of All Wear Parts Friction plates, steel separator plates, sealing gaskets, oil seals, piston rubber diaphragms, bearings and bushings are all replaced with brand-new high-spec aftermarket/OEM equivalent parts.
3. Upgraded Valve Body & Solenoid Assembly Defective original solenoids & worn valve body spools are replaced with new calibrated units, eliminate common shift shudder, hard 2-3 gear shift and pressure loss issues. Integrated TCM control module pre-calibrated for matching vehicle models.
4. Brand-New Torque Converter Included Each set comes with remanufactured torque converter, fully leak-tested and lock-up calibrated to avoid slipping during acceleration.
5. Full Bench Dynamic Load Testing Every finished 6T31 transmission runs 2-hour simulated road load test on professional transmission test bench, inspect line pressure, shift timing, lock-up function and fluid leakage before packaging.
6. Anti-Corrosion Surface Refinishing Transmission housing polished & anti-rust coated as shown in product photos, clean appearance for direct installation.
