OK, so I know WHAT the difference is, but not technically.
What exactly allows the car to shift besides the little up and down part at the shifter?
I want a tiptronic/automatic.. I found a good deal on the right car, but the only downfall is that it doesn't have the tiptronic part. Would it be easy to change? I know people do auto to manual swaps and I figured this is probably a little easier then that too.
