Hot Mode Operation

Transmission fluid temperatures may become excessively high, above approximately 130° C (266° F). When this happens, the PCM modifies its shift pattern and its TCC schedules in order to reduce the heat generated by fluid coupling in the torque converter. These events occur during hot mode operation when the PCM commands the transmission into the lower gear ranges (3rd or 2nd gear) and applies the TCC.

If a situation occurs where a short or open is detected in the circuit, the PCM uses a default value for transmission temperature.
