    Scanner will keep TCC locked on shifts

    We?ve been fighting my 6L80 TCM W/ OS (599) with trying to keep the TCC locked on 2-3 WOT shift. No matter what we?ve tried, it unlocks then locks after shift. However, the scanner allows me to manually lock it and it stays locked like we want. Not sure what else we can do aside from using scanner to lock it while racing.
