Paddle Downshifts When Getting on it?

[PrabhtheStig]

I have had previous car with the +/- feature. Most of them downshift for me when i get on it. Others stay in the same gear.

Ex. 40mph in 4th, floor it and it automatically shifts into 3rd or even 2nd
(to get best accel)

Ex. 40 mph in 4th floor it and it slowly picks up speed in same gear. (how stick is and how cars should be)
I kind of like to HAVE to downshift to get into power band manually


How does this work in the S550's?

When you are in Sport mode and using the paddle shifters, it only automatically downshifts when slowing down beyond the threshold in the computer(which is pretty slow).

Basically it down shifts when it could potentially stall?
Great

When you initially put the trans into sport mode, the computer does all the shifting for you -up and down.

As soon as you hit a paddle shifter while in sport mode, the computer is completely out of the loop shifting. The only exceptions are if the engine is getting ready to stall at low rpms (it will down shift) or if the rpms go too high (the rev limiter kicks in and you lose all power until the rpms are back in the safe range).

To get it back so that the computer takes back over from paddle mode, just shift into drive. Then you can leave it there, or shift back into sport (with the computer once again doing all the work).

If it is in paddle mode and down shifts because of low rpms, I do not know if it stays in computer mode or goes back to paddle mode...
