'04 Surging/Bucking @ constant speed
I have an '04 with just under 10k. Bought new in Oct. When traveling @ steady speeds, (unloaded/not towing) between 45-55, the truck starts surging or bucking. I don't see any variation in RPM's, so I'm thinking it's in the driveline. I just had the truck in for the trans. recall and told them about it prior to the work. They said they reprogrammed some module [img]/ubbthreads/images/graemlins/shrug.gif[/img], but the problem still persists. I was wondering if anyone else has encountered a similar situation and what was done, if anything, to correct it? [img]/ubbthreads/images/graemlins/confused.gif[/img]
