Wow. Glad I found this!!! I have been having the same symptoms on my 2007 expedition. 50-65 light acceleration. Shudders. If I step on it it goes away. Sometimes it does it once sometimes three or four times in sucuession. Never get a studder when slowing down. Fever have been given a check engine light. It's not real violent but definitely a good lunk.


I was really worried that it was the torque converter or transmission.

I hope it's a cop as that sounds better than a rebuild on the tranny.
