Disadvantages of the Toyota U540E gearbox
- This is a very simple and perfectly reliable automatic transmission with a long service life;
- Problems occur only at high mileage and with rare oil changes;
- It usually starts with the valve body simply getting clogged with wear debris;
- Jerking when shifting follows and the clutches in the gearbox start to burn;
- Owners on forums also often criticise the short-lived input and output shaft sensors.
