Hey guys,

I just recently purchased a 2004 F250 5.4 with 100k miles and after driving it for a few days I noticed that while the truck shifts (mainly from 1st to 2nd and 2nd to 3rd) it seems to jerk quite a bit. It does have a pro comp 6" suspension lift on it and I didn't know if the lift maybe put more stress on the transmission causing it to feel more rough, basically I was wondering if this was a sign of the tranny going bad or not, any ideas or advice would be greatly appreciated. Thanks!
