CIRCUIT DESCRIPTION
This sensor detects the rotation speed of the counter gear. By comparing the counter gear speed signal (NC)
with the direct clutch speed sensor signal (NT), the ECM detects the shift timing of the gears and appropriate-
ly controls the engine torque and hydraulic pressure according to various conditions. Thus smooth gear shift-
ing is performed.

Then the ECM compares the actual gear with the shift schedule in the ECM memory to detect mechanical
troubles of the shift solenoid valves and valve body.
