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.
