Purpose/Function
The turbine/input shaft speed sensor detects the rotation speed of the input shaft (low clutch drum).
The output shaft speed sensor detects the rotation speed of the output shaft (primary gear).
The turbine/input shaft speed sensor and output shaft speed sensor signals are used for automatic shift control, manual shift control, and the on-board diagnostic system.
Construction
The turbine/input shaft speed sensor and output shaft speed sensor are both integrated with the TCM and built-into the control valve body.

Operation
The turbine/input shaft speed sensor changes the output signal according to the rotation speed of the low clutch drum.
The output shaft speed sensor changes the output signal according to the rotation speed of the primary gear.

ABS Wheel Speed Sensor And ABS Sensor Rotor
Purpose/Function
The ABS wheel-speed sensor and ABS sensor rotor detect the rotation condition
of each wheel and transmit this information to the DSC HU/CM.
The signal from the ABS wheel-speed sensor is the primary signal that the
DSC HU/CM uses when carrying out control.
