Putting it in Sport mode does not require manually selecting gears, UNTIL you select a gear manually the first time. If you just throw it in S, and never use the up/down buttons, it still auto-shifts for you, but at slightly higher rpm's.
As I mentioned elsewhere, doing this has greatly reduced, if not all but eliminated the shuddering issue I occasionally experienced in 1st gear. I think it somehow re-teaches the software where to shift from 1st to 2nd. Occasionally, just to reinforce this learning process, I will select 1st gear, and keep it there just to run the rpm's up and down to/from 4k. After that, it is good to go for a while.
But, the shuddering my car used to experience did not seem to be clutch slip. It was very noticeable that it was the shift actuators getting confused and engaging/disengaging. With the windows down, I could actually hear the solenoids clicking away.
Good info, thanks. I'll try that today on my way home. I've had the car for 3 months & haven't used the Sport mode once. Look, I guess I was venting a little because I really like the car, it's sporty & has a ton of options but the shuddering deal does bug me. And it's like the last thing I wanna do is leave the car at the dealer for anything. I'm just going to drive it for awhile & see how it goes. If it really starts bothering me again I'll just take it back to the service dept. when I have a day off, during the week. Apparently the transmission specialist at my dealer isn't there on Sat. which makes it difficult for many.
