Yesterday I took my car out for some blasts down the highway. Around 55 I matted it and it shifted from 4th to 3rd and boost came up to 17 and then creeped all the way to around 20. I know this is not supposed to happen and I want to know if there is anything I can do to solve it. If it matters SM read around 779 with 0 knock. Thanks for your time and help!
