Adapter plate enabling the connection (swap / conversion) of the BMW M57N / M57N2 3.0 diesel engine (aluminum block, large bellhousing – M57D30 306D2, 306D3, 306D4, 306D5) with a modern 8-speed automatic transmission ZF 8HP (ZF Friedrichshafen) from BMW – 8HP50 / 8HP51, 8HP70, 8HP75, and 8HP76 (6 bolts), in RWD and xDrive versions.
Do you want to replace the 6-speed automatic or manual transmission in your BMW with an M57N / M57N2 engine (e.g. E60 / E61 530d / 535d, E90 330d / 335d, X5 E53 / E70, X6 E71) with a modern ZF 8HP automatic? Or are you planning an M57N engine swap into another rear-wheel drive BMW? Our adapter is a reliable solution.
BMW M57 / M57N / M57N2 engines are one of the most popular choices for swaps in off-road vehicles and vans – including Jeep (Wrangler, Cherokee, Grand Cherokee), Nissan Patrol (Y60, Y61), and Mercedes Sprinter (campervans and custom builds). Combining a durable inline-6 diesel with an 8-speed ZF 8HP automatic transmission delivers high torque across a wide RPM range, lower fuel consumption, and driving comfort both off-road and on long trips. Gain 8 speeds, fast gear shifts, and the comfort of a modern automatic transmission.
The aluminum gearbox adapter plate was designed to simplify the installation of the ZF 8HP transmission as much as possible. Connecting the engine to the torque converter uses original parts – no additional torque converter adapter plate is needed.

PMC Motorsport parts are intended for motorsport and race track use.
Installation should be carried out by professionals with knowledge in engine swaps and car modifications – in workshops and using properly adapted tools.
The adapter installation manual contains only basic knowledge necessary to physically connect the engine with the gearbox outside the car body.
Depending on your specific car, additional modifications may be required, such as adjusting mounts, engine/gearbox mounts, firewall, transmission tunnel, driveshaft length, etc.
We manufacture our adapters using fully recyclable materials.
To connect the BMW M57N / M57N2 engine with the ZF 8HP gearbox, use the PMC Motorsport gearbox adapter plate and the original (OE) BMW starter ring gear (flexplate) OE 11 22 8 506 670 or 11 22 8 612 144 (not included) together with the torque converter from your ZF 8HP gearbox (6 mounting bolts). No additional torque converter adapter plate is needed.
For installation, use the original BMW M57N / M57N2 starter motor (not included) – grinding of the starter motor housing is required.
For BMW M57N (M57D30 306D2) and M57N2 (M57D30 306D3, 306D4, 306D5) engines with aluminum block and large bellhousing.
For 8-speed ZF 8HP automatic gearboxes from BMW (6 bolts): 8HP50 / 8HP51 (BMW B46, B48, B58), 8HP70 and 8HP75 (BMW N57, B57), 8HP76 (BMW B57, S58), including xDrive versions. The complete list of versions can be found in the table above.
