Transmission overheat p1793

[Gixman05]

After the car had been sitting for a few days the car fridge drained the starter battery dead. Jumped started it and now has come up with transmission overheat p1793 and has locked it in 3rd(trans fail safe prog). This is the second time in 2weeks that I've had to jump start it for the same reason but never had this happen with previous jump starts. Is it just coincidence or have i fried etc. My autel scanner said something like etc module and inpa said p1793 over temperature. It has recently done some heavy towing long distance. Did it with ease and hasn't had any issues till now.
