Abstract

As keeping pressing on the brake pedal for long periods with the transmission (20) shift lever (23) at D position in vehicles, causes the torque converter (25) to churn the ATF (21), and so ATF overheating results which causes serious damages to the transmission (20) operating parts, a monitoring (warning) system (26) is provided. By collecting data from the ATF temperature sensor, transmission shift position sensor, engine speed, vehicle speed, ABS wheels speed sensors, coolant temperature sensor, and Auxiliary fan speed, to feed it into a microprocessor (35), the system carry out three operations. The first: by warning the driver via a warning message how to act, while a warning sound is provided if the driver did not act. The second: by increasing the Auxiliary fan speed. The third: by carrying out calculations of the evaluated remaining age or mileage for the ATF, and warning the driver when to replace it.
