ZF 6-Speed Automatic Gearbox Tuning for BMW

BMW used versions of the ZF 6HP automatic transmission across many petrol and diesel models. Gearbox tuning changes the transmission control strategy; it should be selected for the exact gearbox and vehicle rather than treated as a generic engine remap add-on.

ZF6HP Gearbox Remapping | Faster Shifts | Improved Reliability

Common questions

Will a ZF 6-speed tune fix a slipping or harsh gearbox?

No. Mechanical or hydraulic faults should be diagnosed and repaired before software tuning is considered.

Can gearbox tuning be carried out without an engine remap?

On supported applications, yes. The best setup depends on the standard engine output, existing software and the owner's objectives.
