SENSORS-INPUT SPEED
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
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 sen-
sor N3 (8) records the speed of the front planet carrier
via the internally toothed disc carrier of multiple-disc
clutch K1 (3).
