I had vibration in the rotors at 200km. I drove across Canada to TO and the vibration was so bad I thought the car was going to fall apart LOL!
Print off the TSBs and bring them with you. Mine was obvious, some cases are more subtle.
The trans TSB is for a delayed downshift when you stomp on the gas plus rough shifting. After the trans TSB is applied it also automatically shifts at 6000-6200rpm instead of smacking the rev limiter if you floor it in autostick.
I much prefer the new shifting strategy and the rotors were a night and day difference. The car is perfect to me now and I am loving it.
