Speed Sensing Series - Transmission

Roll Over to Zoom

The speed sensor detects a gear or target wheel in the transmission and generates an electric digital signal proportional to the speed of rotation. The transmission controls use this information to modify the various transmission functions such as shift points and perform diagnostic tests.
