My 04 4.8is makes a big (not like earth shattering, but very noticeable) clung/thunk/thud call it what you want when i mash the throttle from a stop. hill or no hill. sport or not sport mode. is this in fact the "phantom rear ending" people speak of?
i hear the software update fix is available for the 4.4s, what about the 4.8s?
anyone experience this? i have 46k miles.
again, i searched, but it seemed to only apply to a 4.4, not the 4.8.
thanks!
charlie
