Disadvantages of the Toyota A343F gearbox

• This is a robust gearbox, but it is fitted to large SUVs with powerful engines;
• That is why the service life of this transmission depends entirely on how it is driven;
• With an overly active owner the torque converter lockup clutch wears out before 200,000 km;
• The valve body then gets clogged with wear debris and the gearbox jerks and snatches;
• In the most neglected cases shaft vibrations destroy the oil pump bushing.
