Precise control of shift timing, working state of lockup clutch, shift time, transmission oil pressure control, etc. are the main signals of the transmission.

The sensor is based on the hall principle and used in conjunction with the transmission gear to calculate the speed of the transmission input / output shaft. TCU combines the engine speed sensor, output / input shaft speed sensor and other signals according to this value.

It is mounted on the housing near the transmission input / output shaft.
