M156/M157/M177/M272/M273/M278 to ZF 8HP Gearbox Adapter Kit

The PMC Motorsport A-M156-8HP gearbox adapter kit serves as a dedicated solution for connecting Mercedes-Benz M156, M157, M177, M272, M273, and M278 series engines with BMW-spec ZF 8HP70, 8HP75, or 8HP76 automatic transmissions. By bridging the gap between these platforms, it enables advanced drivetrain swaps for motorsport, drift, or performance street use. The adapter features a 20mm (0.78") thickness and is machined for precise coaxial alignment between the engine and gearbox to ensure reliable operation. Each set consists of an aluminum adapter plate, dedicated gearbox adapter bolts, and a crankshaft bolt kit. Please note that this conversion requires an original Mercedes-Benz flexplate/ring gear (specifically OE parts a2730300312, a2730300412, or a2780300112) and a compatible starter, which are not included in the package. Due to the specialized nature of these components, PMC Motorsport mandates that this kit be installed by professionals using appropriate workshop tools. These parts are engineered specifically for motorsport and racetrack environments. The manufacturer verifies quality via ISO PN-EN ISO 9001:2015 certification, with every sub-assembly marked with a serial production number.
