This starts life as a stock ZF transmission 5-speed. It is completely rebuilt to stock specs to make shifting smoother and faster. This transmission can be shifted as fast as a sequential box by an experienced driver!

While the internals are out, all non-friction mesh and bearing surfaces are cleaned through REM® polishing. This isotropic polishing process leaves gears and bearing surfaces mirror smooth, which reduces friction (heat and driveline power loss).

In our cars, we saw a 2-3% reduction in driveline losses on a chassis dyno with this part alone (this equates to 6-10 Hp on an average M3 Prepared class engine!) - plus more time spent accelerating due to faster shifts.

This unit is stock on a E36 M3 and 328, E46 328 and 330, and some others. Can be retrofitted to most race applications. Call with further questions or specifications. Price does not include $900 core charge for an acceptable piece (no junk please!). Customer responsible for return core shipping.

We recommend using Redline ATFD4 fluid.
