This remanufactured K120 FWD (2WD) Direct-Shift CVT transaxle assembly is rebuilt in our transmission factory. K120 CVT is Toyota’s 10-speed simulated CVT with starting gear, widely fitted on 2.0L Corolla E210 and C-HR. This front-wheel drive unit is completely rebuilt, worn internal components replaced, every unit passes full dyno testing. This product is designed for B2B wholesale buyers: auto spare parts exporters, auto parts distributors, auto importers and large auto service groups.

1. Full disassembly & ultrasonic chemical cleaning of all housing and internal mechanical components.
2. Precision measurement of pulley, shaft, clutch pack, valve body and bearing clearances to OEM tolerance limits.
3. Replace most failure-prone consumable parts with brand-new OEM parts, including all oil seals, O-rings, friction plates, bearings and transmission filter.
4. Dynamometer bench test: simulate real vehicle working condition, check oil pressure, shifting logic, torque capacity, vibration and noise.
5. Pressure leak test: pressurize the assembly to check all sealing surfaces to eliminate oil leak risk.
6. Visual final inspection before packaging, protective caps fitted on all fluid ports.
