Normal Operation
The TR sensor assembly is an internally mounted sensor that includes the rooster comb and bracket, located next to the main control valve body. The components of the TR sensor are factory adjusted and the TR sensor must be installed as a calibrated assembly. The TR sensor contains electronic circuitry that provides the TCM a fixed frequency duty cycle for each of the various positions of the manual lever (PARK, REVERSE, NEUTRAL, D, M, 3, 2 and 1) to the TCM. The TCM uses the TR sensor signal for line pressure control, shift scheduling and TCC operation. The TCM sends network messages for engine start enable and reverse lamps.
