Disadvantages of the TB-68LS gearbox

  • This is a reliable and durable transmission, but it is installed with very powerful V8 units;
  • For an active owner, the lubricant quickly becomes contaminated with friction wear products;
  • So change the oil more often or the solenoids in the valve body will not last long;
  • In particularly advanced cases, dirty lubricant destroys the channels in the valve body plate;
  • The weak points of the automatic transmission also include short-lived bushings and the Forward drum.
