Disadvantages of the Toyota UB80 gearbox

  • Owners of gearboxes in the first years of production often complained about lubricant leaks.
  • Otherwise, this is a reliable automatic transmission if you keep its cooling system clean.
  • High temperatures wear out Teflon rings and the oil pressure drops.
  • Then, due to low pressure, the clutches in the bags burn and the gearbox begins to push.
  • Other problems are associated with contamination of the valve body with friction wear products.
