Disadvantages of the Toyota K112 gearbox

  • The weak point of this box is the bearings; sometimes they last less than 100,000 km.
  • The remaining CVT problems are somehow related to contamination of the valve body.
  • When the oil is changed infrequently, the solenoids become clogged and the gearbox begins to operate jerkily.
  • If you do not pay attention to this, then you will face an expensive repair with belt replacement.
  • Keep the cooling system clean, this greatly affects the transmission life.
