okay so it started a couple weeks ago and has gotten to the point where its annoying and whoever gets in my car asks about it, it gets louder the longer i drive the car and does it when im in drive but not moving and on the brakes, in park it does, not in reverse. im positive its coming from the transmission im wondering i f this happens to a lot of them? its a stock trans with 150k on it, fluid changed regularly. any info would help please!
