NEED HELP!! Serviced my Truck, Now it Runs Rough!!

[SJB]

Not sure where to post this, but here it goes.

This doesn't pertain to a diesel, but my '01 Super Duty w/ V10.

Despite thinking about getting a diesel, I decided I still need to maintain my current truck as well. So I recently changed the transmission fluid and filter (in pan and torque converter), changed the fluid in my transfer case, and changed the fluid in both my differentials.

After doing all this, I noticed my truck was driving kind of rough at times. Don't really know how to describe it. But it kind of stutters (maybe even vibrates a little) when I'm lightly on the gas. I didn't really notice this before the service. Was thinking it might have something to do with the tranny (only because the service), but I don't really know. Not sure if it is just a coincidence. Everything went smooth on the service. I used the correct transmission fluid (Super Tech fluid for Dexron III and Mercon brands). I was a little worried about the brand, but the guy at the store told me it should be fine. I put in the right amount of fluid because I measured what came out. The only thing I did when the tranny was empty was put the truck in neutral (while engine off) so I could rotate the torque converter by hand to drain it. Didn't think this would hurt anything.

I also filled up the gas tank recently. Does it sound like a transmission issue, or is it just a coincidence? Could it possibly be bad gas? Any help appreciated.

check around your trans dipstick maybe you knocked something loose not knowingly. if you can get a hold of a scanner and run an key on engine running test would probably be helpful.
