I can't speak to the Ford...and I'm not a diesel owner. My brother-in-law had the transmission go out of a 3/4 Dodge diesel two weeks ago when they were pulling a camper here to visit with us. Still under warranty so they had it towed to a local dealer and my dad pulled his camper to our place. He had to rent a car to take his family home then fly back down last weekend after the transmission was replaced. Again, I'm not a user, but it didn't speak well of the Dodge transmission.
