I didn't think I was bemoaning, I thought it was polite to come back and acknowledge the responses. I'll try to stick to the facts as I am definitely here for advice not pity. The mechanic's theory was that the engine was so hot from clogged radiator that it heated the transmission fluid because the fluid was not burned and only poured out when the engine overheated and stopped with the new radiator. So we got about 60 miles down the road- engine running nice and cool. Stopped at a truck stop to fill up with diesel. 10 miles down the road broke down AGAIN! Engine cool--but stopped getting power. It's like we ran out of gas, like gas wasn't getting to engine or we were stuck in high gear because car shook and was idling high and stopped moving. So now we've been towed to another campground and excursion towed to their truck/auto repair where they willl look in the AM. So disappointing after all the time and expense. So that's all I know: not overheating issue anymore...could they have jarred something during installation? Something weird with full tank of diesel?! Or jarred further by feuling process, or unrelated. "Service Engine Soon" light came on. Head gaskets were checked and previous shop had no codes but maybe now they will...no fluid leaking and the levels are good. Hubby did drive with cruise control on which probably isn't related but I suggested might not be safe...just trying to provide all details!!
