I started the post a few weeks ago regarding the noise when stopped but in gear. Took my truck into the dealer last Wednesday. Called on Friday and they said it was a bad torque converter. Ford sent them a replacement part, and I should have the vehicle possibly today. They want to get it installed and put some miles on it before I get it back. I will update when I get the truck, but it did seem to require more pressure on the brake pedal and when downshifting, from 5 down, it would seem to shift pretty hard and drive up my rpms. Sort of like downshifting when towing. I am hopeful this will fix the problem, as I have sumo springs, pmf sterring stabilzers, replacement bumpers ready to get put on.
