Is it the entire time you are in gear, or only when you first shift into gear?

It does it sometime while in gear. I thought that was from when frost tuned my car.

Im Guessing your Cammed and a A4. My car does the same thing sometimes at lower speeds and going into reverse. My tuner says it cause I havent swapped to a larger stall yet so they dont match up correctly. Now I have the issue but should be solved soon, have 3600 stall and flexplate in the closet, along with 3.73 gear to install as well. Then a complete new Dyno tune

My car does this too but I am not cammed. But its only when I first put it in reverse and when I first put it in drive. I did recently have a tab replaced on my shifter and it started just after that. So I dunno exactly why it does it.1998 Trans Am WS6 - Phantom

mine does it too when i go from park to reverse or to drive, or from reverse to drive or vice versa. it kinda makes a little ping noise when it does it. im gonna check the ujoints this weekend. i also read it could be the epc ( electronic pressure control valve) in the transmission. anyone had problems with this??
