Transmission Fluid Temperature (TFT) Sensor
The transmission range (TR-P) sensor assembly,
shown in Figure 11, is an internally mounted sensor
that includes the detent spring, rooster comb lever and
bracket, located next to the solenoid body and bolted
to the transmission case. The transmission range
sensor is non-adjustable and is not serviced
independently. The TR-P sensor contains electronic
circuitry that provides the PCM a fixed frequency, at a
duty cycle, for each of the seven positions of the
manual shift lever. Refer to Figure 11 for the duty
cycle specifications for the various positions. The
PCM uses the TR-P sensor signal for starting in Park
and Neutral only, reverse lamp operation, and for line
pressure control, shift scheduling and TCC operation.

The transmission fluid temperature (TFT) sensor
twist-locks into the solenoid body and is a
temperature sensitive device called a thermistor. As
the fluid temperature increases, the TFT resistance
decreases, as shown in the chart in Figure 12. The
PCM uses the TFT signal as an input to determine
cold and hot temperature shift scheduling and for
TCC apply and release scheduling.
