I have a 2004 F150 Supercrew. When cruising between 45 - 50 mph, a loud "clunk" can be heard and felt when I try to accelerate. Is anyone else having this problem? I took it inot the dealer, and of course, they told me that they could not reproduce the sound. Any help you could give me would be most appreciated.

 

theres a tsb out for downshifting from 3-2 which im having now

 

Thanks for the update. When I take my truck dealership, should I let them know that there is a tsb?

 

051012 TSB number

 

I took mine in recently for the same problem. According to the dealer, the TSB says the clunk is normal, and not to try and fix...This seems insane to me. I tried to explain to them that it feels like there is slack in the transmission, and sometimes I get a loud "clack" when I accelerate from a coast.

Let me know if your dealer does anything.
