Disadvantages of the Toyota A341H gearbox

  • This is a reliable gearbox, but it is fitted to a large sedan with a powerful V8 engine;
  • That is why the torque converter lockup clutch wears out very quickly under hard driving;
  • The wear debris then clogs the valve body and the automatic transmission starts jerking badly;
  • If you ignore this jerking, the oil pump bushing will be destroyed;
  • Leaks then appear, and the planetary gearset is sensitive to a low oil level.
