Safety Features

To protect the transmission there are temperature programs to prevent overheating. The TCM can choose to raise the shift points and activate lock up more often if the oil temperature is too high.

The reverse gear will not be activated if the car is travelling faster than 7 km/h (4 mph). If the power supply to the solenoids fails, it is still possible to drive the car. The gear position D/M gives 2nd gear and P-R-N will work as usual. In case of a major fault in the transmission, mechanical or electrical, the TCM will cut the supply to the solenoids in a controlled manner (limp home).

In case the TCM detects a failure it will go into emergency mode.
