I just got mine done today.
I've noticed some surging when cruising at 65-75, and I was always annoying by the lack of throttle response when taking off in 1st.
(I don't need a lecture from anyone on how they can take off on a 15% grade in 2 gear without the throttle; I don't care. I could take off in 4th with my old F150 with a straight-six. Not the issue).
Yesterday, on my way home from work, it felt like someone wedged a 2x4 under the gas pedal. I could barely keep it up to 60 on the highway, and I had to leave the car slowly rev through each gear change.
An engine restart fixed it, but I had the dealer look at it (I drive 70 miles a day, don't want to be stranded).
No codes, but they applied the TSB. Fingers crossed.
