I have an 06 lariat 4X4 with 74,000 miles and have a shudder as described but mine seems to shudder more after slowing down and then increasing speed like coming up on a red light and it turns green. Not showing any codes and no check engine lights. Tried seafoam with no change. Talked to a trans mechanic and told me to go to O'Reilly's and ask for "shudderFix". Just put it in at the store and drove 10 miles back home and can definitely feel a difference. Less than $10.00 and hopefully got this remedied for a while.
