Transmission Speed Sensor: Description and Operation
NAG1 TRANSMISSION
INPUT SPEED SENSORS
DESCRIPTION
The input speed sensors (6, 8) (Fig. 165) are fixed to the shell of the control unit via contact blades. The speed sensors are pressed against the
transmission housing (2) by a spring (7) which is held against the valve housing of the shift plate (5). This ensures a defined distance between the
speed sensors and the exciter ring (4).
OPERATION
Signals from the input speed sensors (6, 8) (Fig. 166) are recorded in the transmission control module (TCM) together with the wheel and engine
speeds and other information and are processed into an input signal for electronic control.
