“Other than that, since I pull a trailer, I change the transmission fluid per Ford’s recommendation (the auto trans holds up better than the manual - Ford dropped the manual in 2004 I think).”
My dad bought his F250 new in 2004, and the manual transmission was still available then. He went for the automatic in his.
And amazingly, he’s had no problems with the 6.0L Powerstroke in his truck. The guys who put his engine together must have really been on their game that day!
That engine was so bad it cost Ford almost half it's commercial business, which is a third of Ford's total business. Ford sued International and specified getting to drop their exclusive contract for diesel engines as remedy for the damages. All they wanted was to get out of the contract so they could design their own engine.
There is a lot I like about the new Ford internal design, but not for the $60k price tag to replace mine. I also refuse to buy one with the Diesel Exhaust Fluid crap.
