I have a 2005 ford f150 lariat with a sporadic transmission clunk, also winning noise at speeds 10mph and lower, sometimes when I'm braking, other times not. I've had the transmission rebuilt, a new rear end installed, even put a new pcm in it. New u-joints, New brakes and rotors, and it continues to do the same thing. I'll take it back to the transmission shop, they'll drive it around and nothing will happen. Give it back to me and its starts all over again. The only thing I could imagine it to be is either the bands need adjusting or the anti clunk spring isn't right. I'm at my wits end here because this has been going on for months. Anybody have any ideas what it might be.
