The 6-speed Getrag 420G transmission, found in the European E36 M3 Evolution and E46 M3, has become an increasingly popular swap amongst E36 owners. Its increased strength, longevity, and overdrive sixth gear make it a great choice for both track cars and daily drivers. Unfortunately, many of the components needed to complete this transplant have become hard to source. Despite increased demand from enthusiasts, BMW has blocked the sale of European E36 M3 parts into North America.
Recognizing this issue, we set out to develop a replacement for the unavailable, 420G-specific transmission crossbrace. Our initial investigation revealed that the factory cast aluminum construction was failure-prone, so durable 5GA 1018 steel was chosen to provide a lasting upgrade. The Turner Motorsport Heavy-Duty Transmission Crossmember is finished in a brilliant silver powder coat to resist corrosion and maximize appearance. Despite being much stronger than the factory crossmember, our design is dimensionally identical, ensuring a perfect fit with your six-speed swap.
Design:
Manufactured from durable 5GA 1018 steel - much stronger than OEM cast aluminum construction Finished in brilliant silver powder coating for maximum corrosion resistance Steel gussets are welded to the main bracket for added strength and power-holding capability Integrated locating dowels prevent bushing rotation and ensure proper alignment under load Dimensionally identical to the OEM part - fully compatible with OE-style bushings and factory hardware Features & Benefits:
Direct replacement for Genuine European BMW part number 23702227892 Finished in brilliant silver powder coating for maximum corrosion resistance Retains factory mounting points and driveline geometry for hassle-free installation Product Development:
Our Heavy Duty Transmission Crossmember was designed, engineered, tested, and quality inspected by our Research and Development team. We strive for nothing but the highest level of precision and quality through leading-edge product development technology, including FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modeling, rapid prototyping utilizing our in-house 3D printer, and rigorous long-term product testing.
