talk about automatic.. I have a shiftronic6

When I go thru a 15km stretch of a steep mountain(2000m above sea level) climb. I prefer the shiftronic. I usually cruise at 4th gear * 60-70kph but when I need to overtake a slow moving corolla, downshift 3rd and bam 80kph no clutch no drama... then ease again to 4th or 5th or 6th(minimum 70kph)
