The 7-speed preselective robotic gearbox ZF 7DT-75 was produced in Germany from 2009 to 2016 and was installed only on the first generation of the Porsche Panamera liftback. There is a transmission modification for rear-wheel drive versions 7DT75 and all-wheel drive 7DT75A.
7DT family: 7DT-45, 7DT-70, 7DT-75.

Disadvantages of the ZF 7DT-75 gearbox
- The robotic gearboxes of the first years of production were annoying, but the firmware corrected this.
- Now all problems are related to contamination of the valve body or wear of the solenoids.
- Failures of liquid pressure and temperature sensors also occur periodically.
- Much less often, but sometimes speed or gear position sensors fail.
- If you drive excessively active, the clutch block will have to be replaced up to 50 thousand km.
