[tamari1000]

hello i need help with my 2010 tahoe lt i really love this car but i have one problem when i drive the car sometimes i hear like kicking noise (like when 2 metals hit each other) when the transmission changing gears when i drive 30-40 miles ,i went to chevy dealer twice they check the car and all of that and every time i went there its didn't make that noise it not happen all the time but its annoying and i want to fix it - it is 2010 tahoe i shouldn't have this kind of noise - it also happen to me when i come out of a turn and hit the gas i hear the noise - anybody know anything about it?
those guys from chevy drive the car twice and said the truck is fine - but its coming from time to time
