Yo Mario! Kalle Blomkvist here!
Hope all is well! It seems like you have started to write in english! Great work, now we all can understand you. Yes the AUTO only have gear 1,2,3,4 and D as it is the last gear we have in AUTO. In MANUAL they have six gears. So the easiest part would be to consider the letter D to be your "5". Also, when using the 5th gear at least I do not bother looking at what it says on the gages but on the road.

There is a TCU upgrade from both Eurocharged and Speedriven I believe. And also a great and cool paddle shift updrade.

Now I am off to eat spaghetti with swedish meatballs. Coincidence or what?!?!
