Okay, whenever I am IN gear and get up to about 3k RPM's and let off the gas, as the RPM's go down it will make a chattering/vibrating noise then stop, then as they drop more it does it again. The noise only last about 1 second and does it twice from 3k to idle. If I am just sitting and rev the car up it doesn't do it. Theres no extra play in the transmission and its driving normal other than that. I thought maybe exhaust but all the mounts for it are fine. Just throw in your 2 cents I guess![]()
