Getrag 6-Speed Race Prepared Transmission for E46M3

Core must match the transmission ordered

This starts life as a stock Getrag transmission 6-speed. It is completely rebuilt to better than stock specs to make shifting smoother and faster.

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 E46M3, MZ4 and some others. Call with further questions or specifications. Price does not include $1500 core charge for an acceptable piece (no junk please!). Customer responsible for return core shipping.

We recommend using factory BMW fluid.

Please verify vehicle in order notes.
