Why the optimization is worthwhile for every 6HP – even without performance enhancement

The 6HP automatic transmissions were developed in the early 2000s – with a control behavior that was considered smooth and comfortable at the time. Today, however, the original shifting strategies seem sluggish, slow, and overregulated in direct comparison.

🚗 Modernization instead of tuning: Even without engine optimization, the software upgrade is worthwhile – for everyone who wants a transmission behavior that corresponds to today's standards.

✔ Significantly faster gear changes

✔ Smoother transitions at partial load

✔ Less shifting jolts & nervousness

✔ Optimized fuel consumption values through more precise shifting behavior

The update brings the driving experience noticeably closer to modern F-series vehicles and ensures more driving pleasure – without any mechanical interventions.
