Disadvantages of the TL-80SD gearbox

  • All the problems here are typical for any Aisin automatic transmission from this family;
  • Due to the high torque of a turbo engine, the torque converter clutch wears out quickly;
  • Then this dirt clogs the valve body and shocks appear when switching the gearbox;
  • Driving with a worn clutch breaks the oil pump bushing and causes leaks.
