I have a 2001 Honda civic. Great car, so far. I need to replace the catalytic converter, however I just passed smog shortly prior to the cc going out so I’ve been putting it off (bad, I know).
When I drive in the lower gears, 1st and 2nd, the car makes a much louder than normal ggggrrrrrrr sound. Don’t know quite how to describe it. Especially when turning corners.
Do I need a new transmission? Does my needing to replace the catalytic converter have anything to do with this?
