Disadvantages of the ZF 8HP95 gearbox

  • This reliable and durable gearbox has to work with very powerful engines.
  • During aggressive driving, the solenoids will quickly become clogged with friction wear products.
  • Worn clutches cause vibrations and break the oil pump bearing.
  • Frequent acceleration can cause aluminum parts in the mechanical part of the automatic transmission to burst.
  • The weak point of all gearboxes in this series are rubber gaskets and bushings.
