ok, i have a 2005 Ford F150 Fx4 ext cab. Well i was coming home from work the other day, cruising along on 522 about 65-70 and went to kick it down to passing gear and the power was there but the rear end/yoke made a clunk sound. I know ford has a TSB(technical service bulletin) out on an issue similar to that. My questions are does it cost the customer anything for a TSB and what about a PCM reflash( i know i have to take the diablo programmer off my truck b4 i take it in but do they charge for a PCM reflash? i have the typical wait time when i kick it down into passing gear when the programmers not on it. I guess its due to the electronic throttle. The truck runs and drives great and i dont have any other compliants about it but that clunk makes me worry a lil bit. its not the first time its done it. but it only does it when i mash down on it at speeds over 65 or when im coming up to make a turn and i brake n then as i go into the turn i step on the gas to make it up the hill. any help would be great with this issue. I know a few of you have 04 and newer f150s.
Thanks
Ryan
