This car is an auto transmission. I will try to get more in depth. When driving this morning I was about to go up a hill, so I gave the car more gas.... when the boost was starting to pick up, the speed was not really picking up much at all, "kind of like it was a manual transmission and the clutch was slipping". This is the odd part, if i move it over to sport mode where you can shift from the steering wheel, it shifts normal. Any thoughts off of that???
