Thanks folks, nice to be home. No tranny cooler on it though I have always been well aware of its importance. Never had an overheating indication in any way, probably shows the idiot light wasn't working.
Thanks for the offer Steve but as cool as the Extreme A440F is from all accounts it's time to say goodbye to the automatic. Barb and I discussed it on the way home and it was a short discussion.
Sad to be w/o the truck for the next 3 weeks or so but will have it ready for our return trip to Moab in July. Sadder to have to part with the 55 but it has to go if I'm to pay Safari for their work.
