Disadvantages of the Toyota A342E gearbox

  • First of all, this is a very rare automatic transmission that was fitted only to the Century sedan;
  • But it has no reliability problems and failures occur only at high mileage;
  • With regular oil changes this gearbox runs more than 400,000 km without an overhaul;
  • It is important to keep an eye on the cooling system, as this transmission does not tolerate overheating;
  • And most importantly, avoid buying a gearbox from a tuning project, as it is often used for that.
