Hey guys..got a question..When Im at idle, be it in park or reverse or drive, I hear this "buzzing" noise coming from what appears to be the transmission. Now, to me it sounds like a bearing going bad or something like that. I listened for the same noise around the drivebelt area, but no "buzzing" sound. I only hear it inside the drivers side from where I suppose the differential is located, but Im not sure. Furthermore, I wonder if its just a normal sound these GM trannys make...can someone make light of this??Thanks..
