BMW GS7D36SG DCT Upgrade

The GS7D36SG transmission is a 7-speed dual-clutch transmission (DCT) developed for various BMW models equipped with N55 and S55 inline-6 engines, including the F80 M3, F82 / F83 M4, and F87 M2. 

When enhancing engine performance, it is crucial that the transmission is upgraded as well, ensuring that it will reliably perform under the increase in power generated by the engine.

DEKA excels in providing high-quality transmission upgrades, using expert engineering and the careful replacement of high-wear, OEM components with CNC-machined billet elements, increased frictions, and craftsmen assembly.

Benefits include greater holding power and durability, reduced clutch slippage, and enhanced performance.  

Each level of upgrade provides greater torque rating, offering a unique solution for each build, driver preferences, and budget.
