hey guys, having some problems with my transmission as of recent. The car is a 2015 2SS with an L99 and the 6l80E. The trans does not want to shift at anything above light throttle all the way through wide open. However, the only time it appears to be an issue, is the 2-3 shift. The car has a set of headers, a catback exhaust, a cold air intake, and a street tune from a local performance shop. I brought the car to the tuner first, and he could not find a problem with the tune, and even after resetting the trans to the stock tune, it was still having the same issue. Any, and I mean any, insight will help. I'm pulling my hair out trying to figure out what could be causing this. Just had the trans flushed as well by the dealer at 55k miles.
