Why optimization is worthwhile for every 6HP – even without performance improvement
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 shift strategies seem sluggish, slow, and over-regulated in direct comparison .
🚗 Modernization instead of tuning: Even without engine optimization, the software upgrade is worthwhile – for everyone who wants transmission behavior that corresponds to today's times.
✔ Significantly faster gear changes
✔ Smoother transitions at partial load
✔ Less gear shifting & nervousness
✔ Optimized consumption values through more targeted switching behavior
The update brings the driving experience noticeably closer to modern F-Series vehicles and ensures more driving pleasure – without any mechanical intervention.
