Searching for a TOYOTA Corolla Transmission 2.0 CVT K120 Automatic (M20A-FKS, OEM 30400-12760 / 30400-12740) with precise specifications and verified OEM compatibility? This CVT automatic transmission assembly is engineered to match the drivetrain dynamics, torque characteristics, and advanced electronic control requirements of the Toyota Corolla equipped with the 2.0 L M20A-FKS petrol engine—delivering smooth, seamless acceleration, optimized fuel efficiency, and refined everyday drivability.
Designed specifically for Corolla models powered by the M20A-FKS engine, this K120 continuously variable transmission (CVT) integrates precisely with the engine’s torque curve and Toyota’s modern powertrain control architecture. The system supports optimized ratio control, adaptive pulley logic, and calibrated hydraulic pressure mapping to ensure consistent power delivery, reduced drivetrain stress, and long service life. Seamless communication between the transmission control unit (TCU) and engine control module (ECM) enhances throttle response, shift smoothness, and overall vehicle responsiveness across city driving, highway cruising, and mixed conditions.
Owners commonly search for a replacement TOYOTA Corolla 2.0 CVT Automatic Transmission when experiencing symptoms such as delayed or inconsistent acceleration, CVT shudder, slipping under load, abnormal drivetrain noise or vibration, transmission warning indicators, or reduced fuel economy. Because CVT systems are precision-engineered to operate with specific torque curves, electronic protocols, and hydraulic strategies, confirming the correct specification—especially the K120 CVT type and OEM part numbers 30400-12760 / 30400-12740—before purchase is essential to ensure smooth operation and extended service life.
This CVT automatic transmission assembly is ideal for buyers seeking a direct-fit or OEM-compatible replacement solution that restores factory-level refinement and reliability in compatible Toyota Corolla models. Accurate matching ensures proper electronic synchronisation, correct hydraulic control, and seamless drivetrain integration—helping protect internal components and maintain long-term durability.
Installing an incompatible or incorrectly specified transmission can result in persistent diagnostic fault codes, unpredictable driving behaviour, overheating risk, reduced efficiency, and premature wear of internal CVT components. Ensuring the correct transmission match safeguards the entire drivetrain and helps avoid unnecessary repair costs.
Before purchasing, always verify the vehicle model (TOYOTA Corolla), engine type (2.0 L Petrol M20A-FKS), transmission type (K120 CVT Automatic), and exact OEM part number (30400-12760 / 30400-12740). Proper verification ensures accurate fitment, smooth integration, and dependable performance you can trust mile after mile.
