Description
The output speed sensor is a vital unit that measures the rate of rotation of
the transaxle's turbine shaft and output shaft, and delivers the readings to
the TCM. The sensor provides critical input data that's used in feedback control,
damper clutch control, gear setting control, line pressure control, clutch activation
pressure control, and sensor fault analysis...
