Still having problems manuvering this site so this may be a repeat. I have a 2012 f350 deisel with 960 miles on it. Towed my 5er for the first time and experienced a shutter from 1st to 2nd gear. Second to 6th is smooth. Any Ideas?

 

Your original thread awaits. And it's "shudder" (what you do when you get chills up your spine or are incredibly cold, beyond a simple shiver) not "shutter" which is what you close over your house's windows.

Sounds like you need to shim your carrier bearing.

 

Nope. The other thread has better info. Let's let this one die since I don't think we can lock it.
