Disadvantages of the TB-65SN gearbox

  • This is a reliable automatic transmission without any design flaws;
  • However, typical problems with oil contamination by wear products also apply to it;
  • If you do not regularly update the oil in the automatic transmission, then the solenoids do not last particularly long;
  • In the most advanced cases, dirty lubricant corrodes the channels in the valve body plate;
  • Servicemen also regularly replace the solenoid wiring and oil pump bushing.
