Inhibitor switch ensures the safety at engine start. This switch is installed to the right side of transmission case, and operated by selector lever. When the selector lever is in the "P" or "N" range, the engine will start because the electric circuit in inhibitor switch is closed and the starter circuit is connected. When the selector lever is in the "R", "D", "3", "2" or "1" range, the electric circuit in inhibitor switch is open; therefore, the engine cannot be cranked. In the "R" range, the back-up light will illuminate because the back-up light circuit in the switch is connected. In addition to the functions above, the inhibitor switch has the circuit which detects the selected range position at the present and transmits the range signal to the TCM.

Torque converter turbine speed sensor (output shaft speed sensor) is installed to the outside of transmission case. This sensor detects the turbine speed of torque converter by the peripheral speed of high clutch drum connected to input shaft. And then it transmits the sine wave signal (32 pulses per rev.) to TCM. TCM calculates the ratio of the input shaft speed to vehicle speed, and then makes a judgment whether to shift or not.

This vehicle speed sensor (output shaft speed sensor) is installed to the outside of transmission case.

This sensor detects the front wheel speed, and transmits the sine wave signal (32 pulses per rev.) to TCM.

TCM converts the signal to pulse signal, and transmits to both of the ECM and the combination meter.
