First off love the name, lol. Ok I've read somethings where the Interior Lights are connected to the same circuit as the TCC and beings the Lights has a short somewhere and keeps blowing the fuse, i think that is why it sets off the TCC code. But, why would after cleaning the MAF make the car run great then all of a sudden starts happening again? I feel like there is something else and not the Trans.
