A/T CONTROL SYSTEM: A/T Fluid Temperature Sensor

The A/T fluid temperature sensor detects the A/T fluid temperature and transmits a signal to the TCM.

At Low Fluid Temperature

When the A/T fluid temperature drops below the prescribed temperature, in order to speed up the action of each friction element, the line pressure is set higher than the normal line pressure characteristic.
