FA20DIT 2015–2021 Subaru WRX Automatic CVT TR690GB9CA Transmission & Rear Differential – Low Mileage JDM Replacement

Restore the power, reliability, and smooth all-wheel-drive performance of your Subaru WRX with a clean, low-mileage JDM FA20DIT Automatic CVT Transmission (TR690GB9CA) and matching Rear Differential, imported directly from Japan and sold by J-Spec Auto Sports Inc. This complete drivetrain package is a perfect direct replacement for 2015–2021 Subaru WRX 2.0L models equipped with the FA20DIT turbo engine and Lineartronic CVT transmission.

The TR690GB9CA CVT transmission is engineered to handle the WRX’s turbocharged torque while delivering smooth power delivery, quick engagement, and strong AWD traction. Many U.S.-market WRXs suffer from high-mileage CVT wear, slipping, delayed engagement, and differential noise — making this low-mileage JDM replacement the most cost-effective and reliable solution.

Each unit is sourced from low-use Japanese domestic vehicles, where strict maintenance standards and shorter travel distances keep drivetrain components exceptionally clean. The transmission and rear differential are tested, inspected, and matched together, ensuring proper gear ratio compatibility, smooth AWD operation, and factory-correct fitment.

This package is ideal for WRX owners dealing with transmission failure, shuddering, CVT overheating, or differential whining. With far fewer miles than typical U.S. replacements, this JDM transmission/diff combo provides long-term reliability and restores your WRX to its original performance.
