I have a 05 F-250 w/ a 6.0 Powerstroke that when towing a trailer @ 2000 rpms it is fine but when it down shifts when going up a hill @ 65 mph or higher the moter will chug and it blows black smoke. If you let off the throttle alittle it stops but as soon as you push on the throttle again and it downshifts it will do it again. Also it only seems to do it after I've been driving for about a 1/2 hour. Has anyone had this problem B4 and if so what is the cause (Ford dealer can't seem to find the problem):confused:

I have a 7.3l psd, I have found lots of help at ford-trucks. com. It is a very extensive forum and the guys are all very helpfull to other ford owners. I am just learning diesel as I just bought this vehicle 2 months ago. good luck
