AT hard shift on V5 valet mode

I am running V5 3-30 beta daily and everything is perfect after the gasX fix! Last week I decide to run the valet map for dealer visit and to see how much difference from my map1 setting. Right after I switch to Valet map I can feel the torque impact from the 2rd to 3rd shift and sometimes 3rd to 4th too... which is not happen on the map1 and 2! I thought it's cause by the adaption, but still happen after few days of intensive driving... . Anyone feel the same?

Your transmission control unit adapted to v5 boost/throttle control. So going to back to valet/stock will make it shift less smooth. Not terribly so but noticeable if you're sensitive to that kind of thing. And 6AT transmission adaptations are slow. You can speed things up by doing a 6AT transmission reset through the command center.
