Yes, he puts one pint of tranny fluid each time he changes the oil. This guy that was telling him this is a GM mechanic and he said that three or four oil changes is all it will take and that it will probably stop all together. He's on his second oil change now and it's not ticking anymore. I will probably try it with mine the next time mine is due for an oil change.

Please keep us posted to what they tell you. Thank you for the update.
