Not one to worry, but i've been experiencing a few strange thing's with my 04 PSD,AT (2/04 build date). First, the tran's has a delayed engagement when shifting from reverse to forward, or vis-a-vis. This has happened a few time's. Second, upon starting a warm engine, it let out with a hiccup/burp, it ran fine after that. This has happened once. Third, i was stopped at a light, and i felt like i was rear ended by a Toyota Corolla (throttle surge?), did'nt find anything under my spare tire. I have plenty of time left on my warrantee, so i'm not overly concerned at this point. I prefer not to return to the dealer so quickly, for fear that they will perform unnecessary surgery, i've had this happen with a new Bronco.http://campaigns.ford-trucks.net/forums/images/icons/icon9.gif
