1st noticed this "issue" after last phase of the break in procedure. When using paddles or in manual mode, while in Track or Sport, when shifting from 4th to 5th gear at over 3,250 RPM, the car while buck slightly going in to 5th. It's almost like fuel is being cut off for a millisecond. Manual shifts under 3,000 RPM are fine. All other shifts in manual are butter smooth. While in AUTO, shifts are flawless. Taking to dealer on Monday to get checked out. Anyone have similar issue?
