I have always had one auto and one manual in my garage since 1967. I have had only one problem with an auto and that was an 82 Pontiac Phoenix. The 80's were the time period when GM autos self distructed on comand.
If you treat an auto right it will (in general) go well over 100K with no problems. Also auto's are easier on the engine. So in general the engine will give a longer life with an auto.
