Looking at a new cab and chassis with a 6.7l powerstroke with automatic transmission. Does anybody know anything about these? Ive never had a ford other than the old beater i have now, always had GMs. Wasnt even thinking about a new truck, but the dealership says they have Lifetime warranty on the powertrain if i keep it seviced according to there maintanence schedule. Not sure about that either but cant find a flaw in what they offer, has anyone had any dealings with anything like that?
