But if the car is auto-shifting and reving up to 6k rpm or more, it should be safe right? I was told that the DCT cannot be damaged by shifting, as well as it can't stall out. That being said, anything that it's doing automatically I pressume is safe?
So S-auto doesn't ever shift up to 6th? Even If I redline in 5th lol? I guess i'll have to find out for myself one day haha.
Unlikely you'll ever hit redline in 5th (not even sure the car is capable of doing so), but I think the car has two strategies to avoid over-revving. The first as you may have experienced is commanding an upshift of the transmission. The second is to cut off fuel supply to the engine, which I presume is what would happen if you hit redline in S/5.
Ultimately, the engine is well-protected against exceeding the redline. Unless you have a manual and make a really ill-advised downshift...
