Shifting from D to S while in motion in an auto transmission

Hey everyone. So I recently bought a 2012 blue candy focus titanium hatchback and it's awesome. Quick question though, is it alright to shift to and from S & D while the car is moving? Will I rip the transmission apart if I shift from D to S while on the freeway or something? And what about N? Is that off limits while the car is moving like R and P or is that okay too? Thanks!

Not sure about N, but yes D to S is fine, I have never had any issues and it is not a mechanical switch on the engine, just changes settings in software.

I wonder too about shifting from N back into D while moving. It's fine on a pure manual tranny, but the driver is deciding which gear to shift into before engaging the clutch. On the DCT how does the computer know what gear to choose before engaging the corresponding clutch? Theoretically it could sense the speed the car is travelling at and choose the gear based on that. Anyone know for sure?

Not sure about the N to D but as far as S to D its no problem, the car can sense the speed and gear and when shifted back to D you will not notice a difference

OK so you guys are personally guaranteeing I can shift from N to D while in motion and my DCT won't end up in the rear view mirror?

It might just by chance anyhow

Should be no issues going from D->N or N->D while in motion. Car will detect the speed, pick the highest gear, and engage it.

You're asking us to guarantee you something that Ford employees and engineers can't even do themselves.This message board is full of experiences and weird behavior of this transmission.If Ford technicians can't agree on what's normal or not with this transmission,we as users and former users can't guarantee you anything.Refer to your owners manual or call the dealership if you got any doubts.

I often shift from D to S while driving(usually to down shift if i want to accelerate or if theres a big hill coming) and I have had no problems with it. shifting from D to N shouldn't be a be a problem at all, however, im not sure about N to D. It may vary from car to car because of the different trannys but it seems like people are saying its fine^
