I actually have a few questions. First, a couple of weeks

Customer Question

Hi. I actually have a few questions. First, a couple of weeks ago while driving, my 02 deville went to shift into od. When doing so it started making a loud noise and wouldn't shift into od. Since then, my car won't shift into od until its warmed up. Now the car is idling very rough but, not all of the time. When it does run rough it's usually when it's warmed up and ranges from 475-700 rpms The check engine light has not come on yet either. I ran the internal diagnostic with nothing and hooked up an obd2 scanner showing 2 monitors n/a, 6 ok, and 3 Inc. Any suggestions?

We are only allowed to help with one car system per post. Would you like me to help with the transmission or the idle speed concern?
