I was going up a big grade under maby half throttle not even on my Efi econ tune and going into 6th it seemed to rev a little then shift so was kinda weird and then tried to get to do agin and going into 6th it like double shifted felt like it shifted then rpm went down never done it before goes into second pretty hard sometimes on high tunes going hard but I think im spinning a little when it shifts

Im going to say that its the trans shifting into 6th and then the TC locking up after the shift dropping the rpm's again. I would say its normal
