I'm 19,736. It's a very faint sound at first. Keep windows up and radio off. I've had no other symptoms that seem to be trans related other than this "soft" noise.
The clicking moves with the speed of the car, does it in any gear, clutch in our out, ac/blower on and off. Can't hear after about 10 mph during acceleration. I've shared with the dealer the posts that seem to relate to this, like CV joint.
