Hi;
I am a newbie. I have an 02 Lancer OZ Rally, bright yellow. I bought it new and have 141,000 miles on it. It has been a gem of a car. Quick, but not too quick, nimble and fun to drive. I have changed the fan belts, O2 sensors, PCV, brakes, plugs and oil. I am having a little trouble with my AT tranny. I am glad this board is open, cuz, I think I can get some good info here. I had my transmission diagnosed by the local tranny shop andthey came up with an undocumented code 00016. Where can I get information on undocumented codes.

Thanks to all.
