If I press the accelerator when my truck is at a speed of ~18-28 mph and coasting, I hear a loud clunk (or thunk) as the transmission "re-engages". It doesn't seem to matter if I mash down on the pedal or if I depress it gently. The Ford service tech told me that this is normal because the control chip "disengages" the tranny while waiting to see if I'm going to brake (decelerate) or resume accelerating. In any case, they've put me in the transmission queue to have it checked next week.

Any thoughts or comments from anyone?

a great place to get the real scoop on the transmission thing is to go to the transmission message board on this site, and get a message to factory_tech,, he hangs out on that board, he is a ford factory transmission tech who works with the transmissions at the factory, he has always given the straight scoop, and in depth answers to most of our questions, he can tell you if your dealer is giving you the straight scoop or stroking you. he's a wealth of transmission information. try him there,, i have heard of this happening to other guys on the site as well. your not alone..

I have the same thing happen, when I let off the gas and coast a bit then add some power I get a CLUNK like the transmission is floating between 1st and 2nd and then clunk, it engages hard into 1st gear. I dose not happen any other time. I have not checked with the dealer yet, I'll let you know what I find out.
