Restore the power and drivability of your Subaru with a clean, low-mileage JDM TV1B5MBWAB automatic transmission, imported directly from Japan and offered by J-Spec Auto Sports Inc. This OEM JDM 4-speed automatic gearbox is a direct replacement for 2003–2005 Subaru Impreza WRX and Forester SG5 / SG9 2.0L Turbo models equipped with the matching automatic transmission.

The TV1B5MBWAB transmission is known for its smooth shifting, strong torque handling, and excellent long-term reliability. Our JDM units are hand-selected from low-mileage donor vehicles in Japan, where strict inspection laws and shorter commuting distances help keep drivetrain components in far better condition than their U.S. counterparts.

Each transmission we import is fully inspected and compression-tested (where applicable) to ensure top mechanical condition. This gearbox arrives clean, complete, and ready for installation—ideal for replacing a slipping unit, a failed torque converter, or internal wear commonly seen in higher-mileage U.S. transmissions.

Whether you’re restoring a WRX, refreshing a Forester XT, or repairing a daily driver, this JDM TV1B5MBWAB transmission delivers reliable OEM performance at an excellent value.
