Did you ever get this resolved??I have it set on P1 T5.
Took it for a ride this morning and tried all the different modes, tried hitting the lever as fast as possible and off it as fast as possible, tried hitting the lever fast and not backing off it after it shifted.
It does it the worst going from 2,3,4.
4 to 5 and 5 to 6 are not too bad, but then again i'm not high in the rev range enough to really know!
She is going back to the dealer this afternoon, and if they say nothing is wrong again then they can take it off.
