Disadvantages of the VW AL950 gearbox

  • The modification for Phaeton had weak mechatronics and was often replaced under warranty.
  • Otherwise, this is a very reliable automatic transmission, but it is installed with particularly powerful engines.
  • The torque converter locking clutch wears out quickly and the valve body becomes clogged with dirt.
  • Also, wear of the clutch causes vibrations and they break the oil pump bearing.
  • The remaining gearbox problems are associated with short-lived bushings or leaks.
