Sensor functions
* Input Shaft Speed Sensor: Measures the rotational speed of the transmission input shaft.
*Output Shaft Speed Sensor: Measures the rotational speed of the transmission output shaft.
* Gear selector position sensor: Detects the selected gear selector position (P, R, N, D, S).
* Throttle position sensor: Measures the position of the throttle valve.
* Shift Position Sensor: Detects the selected gear (on some models).
* Automatic transmission fluid pressure sensor: Measures the automatic transmission fluid pressure.
* Automatic transmission fluid temperature sensor: Measures the temperature of the automatic transmission fluid.
* Vehicle Speed Sensor: Measures the speed of the vehicle.
* Engine Speed Sensor: Measures engine speed.
* Crankshaft Position Sensor: Detects the position of the crankshaft and is used for ignition timing.
These sensors provide the transmission control module (TCM) with the information it needs to determine current conditions and control shifting correctly.
