I have an 04 lincoln LS V8, and I was driving to work tonight and I was using the manual :q:q:q:q mode on my car when it got stuck in third gear. Now this isn't the first time this has happened, but I did not realize it at the time, because my radio was up pretty loud and I was driving a for a good amount of time at a high RMP. Now my car when I start it up when it's cold has a knock in the motor and when it's warmed up it knocks at over 3000 RPM's. Do you guys think it's a blown motor?
