2013 GMC Sierra 1500 SL 4.8L 1-2 Shift
Posted to GM Transmission on 5/13/2014 14 Replies

Hello, I have a 6L90 that slips for just a second when taking off in first gear, I was just wondering if an adaptive relearn would fix this or if it was a symptom of a stuck valve, or the wrong Torque convertor???
