this problem sound simmilar to mine, any ideas if the flush or levels are ok? I have a 2001 f150 4wd with 5.4lt engine. the transmission seems to be slipping but i am not sure. when i back off of the accellerator and coast for a moment or two and then apply the gas is bucks or jumps a little like i am on a rough road. what does this sound like all of you?
