A method for monitoring the temperature of a transmission of a vehicle

A process for temperature monitoring a transmission of a vehicle by means of a transmission control device which is arranged on a printed circuit board (1) electronic components (5, 14 and 19) and temperature detecting sensors (3, 3 *, 4), the signals of one or more control modules (14, be 19) supplied with which actuators (26, 27, 28) actuatable power amplifiers (35, 36, 37) are controllable, characterized in that a first temperature sensor (3), the temperature of a hydraulic medium and a second temperature sensor (4), the temperature a contact face of a transmission control device detected with an automatic transmission, wherein a microcontroller (5) (.mu.C) redundant shutdown paths (12, 13) with the control blocks (14, 19) is coupled.
