Hey everyone I’m trying to troubleshoot an issue that started about a month ago and need some help. So... The shudder/vibration only happens when the vehicle is in park. It doesn’t happen when idling in drive, in neutral, accelerating, or anything in between. My rig has over 200,000 miles and this is the first time experiencing it. I ran diagnostics and no codes. I do all my own maintenance and I’ve double everything. Can anyone help me out?
