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.
