Just completed my first major trip, about 6.5hrs of driving. All in all, this thing is great, comfortable, super peppy, great response. Only three issues I had, Sync 3.4 usability, crosswinds that made this thing feel like I was driving an RV, and the tranny. All in all the tranny was comfortable as I'll get out and did great on mountain passes, until.... Was doing about 82mph, 10th gear, had a semi in the right lane that needed to get over for someone merging on. Car was driving via ACC, slammed on the gas, and had this nasty hard shift that basically shook the car. It found 8th gear and accelerated fine, but it scared the wife it was so bad and frankly, I didn't like it much.
I did try searching through the forum and found a few articles, they just didn't seem to be the same situation or experience.
Anyone experience this? Is it normal with this 10speed? Was running in normal 2WD mode, no programming, etc. subsequent slams produce similar responses. Never had issues like this so far, had it since Nov.
On a side note, even with crazy winds, several passes, and cruising above 80mph most of the time (with ACC), I managed to maintain around 21mpg. Well over 50% better than my previous V8 rig with with multi-displacement tech. Very happy there.
