Disadvantages of the VW AL951 gearbox

  • This is a reliable and durable automatic transmission, but is combined with very powerful engines.
  • And the torque converter lock-up clutch wears out quite quickly for active owners.
  • Then its wear products clog the solenoids, so renew the lubricant more often.
  • Abrupt starts greatly reduce the life of aluminum mechanical parts.
  • Other problems are associated with wear of plastic and rubber parts due to overheating.
