I have already checked the battery it is giving 12v in cold when the error happens, does not seems to be the battery.
You might see if you can measure the temperature of the trans housing to find out what temperature it is after sitting 10 hours.

Once I was going to do a drain and fill on the transmission. I ran a short trip and then figured after 6 hours it would be cool enough to work on. No way! Still very hot.

I don't think it is the battery. If you have a charger you might "top off" the battery with a charge before starting it cold to see if that makes a difference.
