Disadvantages of the TR-82SD gearbox

  • This is a very reliable automatic transmission, but it is installed with powerful turbo engines and diesel engines;
  • Because of this, the torque converter locking clutch quickly wears out and contaminates the valve body;
  • Then strong vibrations appear that break the oil pump bushing;
  • If you do not change the lubricant every 30,000 km, then you will have to rebuild the gearbox at 100,000 km;
  • It is also important to keep the cooling system clean; this gearbox does not tolerate overheating.
