Pfitzner Performance Gearboxes is the only manufacturer to offer a motorsport-proven high performance, 6-speed sequential system upgrade for TREMEC T56, TR-6060, Magnum and Magnum XL in-line and transaxle transmissions.

The gear sets are designed to directly replace the internal workings of the standard gearbox and therefore, drop straight into the original casings. No modifications have to be made to the clutch, drive shafts, linkages, mountings or mating surfaces. They also integrate with OEM and motorsport ECU systems, meaning that installation becomes a straightforward, like-for-like exchange operation.
