Disadvantages of the ZF 8HP50 gearbox

  • The main problem is clogging of the solenoids with friction wear products.
  • Due to dirt-clogged solenoids, oil pressure decreases and the gearbox begins to push.
  • If you do not pay attention to the vibrations of the automatic transmission, the oil pump bearing will break.
  • During aggressive driving, aluminum drums often fail and burst.
  • The weak point of the gearbox of this family is the bushings and rubber gaskets.
