Restore factory performance to your Subaru BRZ with this JDM 6-speed automatic transmission (6AT), part number 31009JB000, specifically designed for 2013–2018 Subaru BRZ rear-wheel-drive models. This OEM transmission is sourced directly from Japan and features low mileage, having been pulled from a run-and-drive JDM donor vehicle. It has been fully tested and inspected for quality and reliability by the expert team at J-Spec Auto Sports.

This 6-speed automatic RWD transmission is built to pair with the FA20 2.0L flat-four engine and is known for its smooth shifting, reliable clutch packs, and adaptive logic shift programming. It’s ideal for BRZ owners facing transmission failure, slipping gears, or internal damage—offering a direct-fit solution without the hassle of rebuilding.

The 31009JB000 transmission maintains factory gearing and fitment for all trims of the Subaru BRZ from 2013 to 2018, including Premium and Limited models. You can reuse your existing torque converter, TCU, and wiring harness for a seamless swap.

This unit is thoroughly compression and operationally tested prior to shipment, and backed by J-Spec Auto’s 90-day startup warranty. We ensure every drivetrain component we import meets our performance standards before being offered to customers.

Why buy rebuilt or used domestic transmissions with uncertain history? JDM units typically come with fewer miles due to strict inspection and mileage limits in Japan—making them a smarter, longer-lasting option for your BRZ.
