id051701360800

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.
