OPERATION
PARK/NEUTRAL CONTACT
In selector lever positions "P" and "N" the park/neutral
contact (4) is actuated by a cam track which is located
on the detent plate. The permanent magnet (3) is
moved away from the dry-reed contact (4). The dry-
reed contact (4) is opened. The TCM receives an
electric signal. The circuit to the starter in the selector
lever positions "P" and "N" is closed.
OPERATION - TRANSMISSION TEMPERATURE SENSOR
The temperature of the transmission oil has a consid-
erable effect on the shifting time and therefore the
shift quality. By measuring the oil temperature, shift
operations can be optimized in all temperature ranges.
The transmission oil temperature sensor (1) is
switched in series with the park/neutral contact. The
temperature signal is transferred to the TCM only
when the dry-reed contact of the park/neutral contact
is closed in REVERSE or a forward gear position.
Refer to the Transmission Temperature Sensor Speci-
fications table for the relationship between transmis-
sion temperature, sensor voltage, and sensor
resistance.
