The ZF 8HP51 transmission is an 8-speed automatic transmission developed for various BMW models equipped with the B58 inline-6 engine, including the 240M, 340M, 540, 840, X3, X4, X5, X6

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.
