I just bought an 06 F350, FX4, 6.0, CC
, with 325/65/18 tires, a couple weeks ago. I've only put 600 miles on it, it has 116,000. Right before I bought it, it had: head studs, Ford head gaskets, all 8 injectors, EGR
cooler, all done by a Ford dealer where the truck was bought new and serviced. I checked the transmission fluid before we brought it home, and it was red, and maybe 1/2 qt low. I have not checked it on this trip. It ran fine all the way home, but it was flat ground. And now on a trip to Missouri, in the hills, with the cruise on, it kind of bucks and jerks, as the cruise is trying to maintain the speed at 70 mph. I can make it do it without the cruise by trying to maintain the speed up the hill. If I just ease up the hill and loose some mph by the top, I don't have this problem. Only when the cruise is trying to maintain the speed, or I try to maintain the speed, does it do it. The tach does not change when this is going on. Depending on the size of the hill, it will do it one time, maybe twice. If it does it twice in one hill, I turn the cruise off and run it myself and let it loose a little speed. I plan on towing a 14,000 lb
boat so I'd like to get this resolved before then. I have not changed any filters of any kind yet, that's this coming week. Can anybody tell me which Mercon and where to get it? I've read it's only available from Ford, unless you run something like Amzoil. I have a Scangauge 2 hooked up but have not checked for codes yet. I do not have CEL
showing. Hopefully it's a solenoid or something I can replace.
