Transmissions / Gearboxes

Design 911 offers a curated selection of used Porsche gearboxes and transmissions, with a strong focus on classic air-cooled models. Our stock typically includes 4-speed, 5-speed, and G50 gearboxes from iconic models such as the 911, 912, 930, 964, and 993, along with occasional units from later water-cooled cars.

Whether you're restoring a vintage 911, upgrading to a stronger transmission, or replacing a worn unit, our range includes many legendary configurations—including early 901 gearboxes, 915 units, and various G50 transmissions. These parts are ideal for period-correct restorations, resto-mods, and motorsport builds.

Each listing typically includes model compatibility, basic condition notes, and photos where available. As these are used parts, we encourage you to read each description carefully. 

If you're searching for a specific transmission code, model year, or application, our experienced team is here to help. Please don’t hesitate to get in touch!
