Turbine Speed Sensor 1 And 2

This speed sensor uses the hall element type sensor. The turbine speed sensor 1 detects the front sun gear speed, the turbine speed sensor 2 detects the front carrier speed, and then both send pulse signal (60 pulses per one turn) to TCM. From these two speed values, turbine speed is calculated and is used for shifting control.
