if its a triptronic, then using the triptronic or sport mode, instead of just using the auto mode,
its fine, they use solinoids to shift the gears, and also its not like an old school auto box, the sequential boxes use clutches like a manual, when you are in first gear, the clutch is already on in 2nd, when u are in 2nd the 3rd gear clutch activates, waiting for the solinoid to be activated.
1,3,5 use the same clutch, and 2,4,R has its own clutch so when the solinoid activates to shift the gear the clutch engadges, thats not how the old school auto gearboxes work.
they are designed to be used in the way they are made, but your dad is right talking about old old auto gearboxes using 1,2,3, D in old boxes to screw up the tranny, unless u install a manual shift kit in them.
all the people that replied in this thread were just talking so much shit, the guy was asking a real question about cars, it just shows how many keyboard warriors are on here. you all try to sound knowlagable when ppl ask about the game, but when it comes to real life Q's you just fill the thread with useless bullcrap
