Searching for a genuine CVT automatic transmission assembly engineered to fit the Toyota Alphard / Toyota HV 2.4 L petrol powered by the 2AZ-FE engine, with OEM transmission part number 30400-58010? You’re in the right place.
This Continuously Variable Transmission (CVT) automatic unit is precision-engineered to match the drivetrain specifications of the Alphard’s 2.4 L petrol platform — designed to deliver smooth, seamless acceleration, efficient power delivery, and dependable long-term performance across city driving, highway cruising, and everyday use. Engineered for precise integration with the 2AZ-FE engine output, torque converter behaviour, and transmission control logic, this CVT helps restore refined drivability, consistent throttle response, and reliable performance expected from a factory-matched drivetrain.
Why Replacement Transmissions Are Sought
Owners commonly search for a Toyota Alphard or HV automatic transmission replacement when experiencing symptoms such as delayed, slipping, or inconsistent acceleration, unusual noise, vibration, or “shudder” during gear transitions, erratic RPM behaviour or belt/chain shudder under load, CVT-related warning lights or diagnostic fault codes, reduced fuel economy or inconsistent torque delivery.
CVT automatic transmissions are precision-tuned systems that integrate tightly with engine management, torque converter calibration, and transmission control module (TCM) logic. Ensuring correct fitment and specification matching before purchase is essential to achieve optimal performance, smooth drivability, and long service life.
Why Transmission Fitment & Specification Matching Matters
This Toyota Alphard / HV 2.4 L petrol CVT automatic transmission (30400-58010) is ideal for buyers searching for a Toyota Alphard automatic transmission, a Toyota HV CVT gearbox, a direct OEM-compatible transmission solution, or a replacement that restores factory-matched performance and drivability.
Automatic transmissions — especially CVTs — must align precisely with engine output and torque characteristics of the 2AZ-FE drivetrain, torque converter calibration and CVT ratio mapping, transmission control logic and TCM communication, ECU/TCM sensor integration and drivetrain coordination.
Installing a mismatched or incompatible unit can result in persistent warning lights, rough or unpredictable power delivery, reduced fuel economy, overheating risk, erratic throttle response, and premature wear or early component failure.
Before Purchasing, Always Confirm
Compatible vehicle model, generation, and drivetrain layout (Toyota Alphard / Toyota HV)
Exact transmission variant (CVT automatic) and OEM part number 30400-58010
Wiring harness and mounting compatibility
Control-module (ECU/TCM) calibration and software integration
Verifying these details ensures precise fitment, seamless ECU/TCM communication, and dependable long-term performance you can trust — whether you’re replacing a worn unit or restoring smooth, factory-matched drivability and reliability.
