I just picked up my truck after having a shop install a new DTT TC and now have a vibration at idle that was not there before. The vibration isn't bad but quite noticeable. It goes away by 950 rpm and is present in park, neutral or any gear. The only thing changed was the TC as I'm going to do the VB myself this week. It's Sat. now and I wont be able to get Bill K until Mon. so I was wondering if any one else has had this and is it normal. Thanks.
