That code probably has nothing to do with the recall. The flash is for the PCM not the TCM. Since it's intermittent and the description has the word circuit, check the wiring first. If you have a bluetooth scanner and an appropriate app, you can monitor transmission fluid temps. The sensor is under the valve body cover. It isn't available as a separate part. You could get the temp sensor from a self serve junkyard.

Theory of Operation
The purpose of this diagnostic is to check the electrical performance of the transmission fluid temperature (TFT) sensor circuit. The TFT sensor is an analog device for which the TCM performs A/D conversion every 80 msec. The malfunction conditions detected by this diagnostic include shorted to battery, short to ground, and open circuit failures. If the TFT sensor circuit is out of range high (shorted to battery or open circuit) or out of range low (shorted to ground), a fault is detected.
•When Monitored:
System voltage greater than 9.0 Volts.
Engine rpm greater than 400 rpm.
No other transmission temperature sensor DTCs.
•Set Condition:
Transmission fluid temperature voltage is greater than 3.26 volts for more than 5 seconds.
