Transmission Speed Sensor: Description and Operation
NAG1 Automatic Transmission
Description
DESCRIPTION
The input speed sensors (6, 8) 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
OPERATION
Signals from the input speed sensors (6, 8) 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.
Input speed sensor N2 (6) records the speed of the front sun gear via the externally toothed disc carrier of the multiple-disc clutch K1 (10) and input
speed sensor N3 (8) records the speed of the front planet carrier via the internally toothed disc carrier of multiple-disc clutch K1 (3).
