If you are towing behind an RV (flat towing) - stop. It overheats the transmission. Also, the 2nd & 4th gear band are a weak design in this CD4E transmission. Google - "CD4E band failure" or CD4E O/D Light flashing and you will see issues and outside fixes. Make sure you have a trans cooler in front of your radiator. Not all got them. Option on some versions.
