Ok guys, curious your thoughts on what exactly needs to be done to eliminate a nasty 2-3 shift flare under part throttle in a 6L80E G8. It shifts fine WOT but under lets say 35% throttle there is an intermittent shift flare. Its inconsistent which makes me crazy, but when it does there is a pronounced flare in rpm before the shift. This is on a 100% stock calibration. Any advise is appreciated.
