Part: Transmission

Video tutorial

To reset the MMT gearbox installed on Toyota vehicles, you will need to turn the key to start the instrument panel, checking that the warning light indicating a fault in the automatic transmission is displayed on the instrument panel. To turn off this warning light and unlock the gearbox, you will need to press the clutch pedal and apply some pressure on the brake pedal.

In this way, you will be able to turn the key counterclockwise and turn off the instrument panel: when you turn it back on, the warning light will be gone from the panel and the now restored automatic transmission can be used.
