Trans has never been serviced. I expect to do that at the 100k mark. This car has been drop dead reliable since new. I have maintained it and it's always been garaged.
You sound like me
And me...
So let me tell you my story. I have a 2021 GT/CS 10R80. The shifts were horrible when I bought it used with 11K on the odometer. One of the first things I did was use FORscan to reset the adaptive learning table. Then it drove worse for a while as it was relearning shifts. Took about 1000 miles for it to smooth out. It did get better than when I got the car, but it still had jerky shifts. Then I learned of the Ford Performance kit. I wasn't keen on installing a cold air kit, 87mm throttle body, and locking the tune to 91 octane. But the big improvement from what I learned, was what it does for the transmission. After I installed the kit, and of course it resets the KAM and the Adaptive table, you'll be surprised at how smooth the transmission runs. Be aware that the learning process must be preformed for each driving mode. Normal for me now the car almost perfect, Sport mode, the S position on the shifter, is my preferred mode. In sport, shifts are firmer but not clunky, shift revs are higher and linger a bit longer. And most of all it's not hunting for the highest gear possible. The Ford performance kit made a very positive difference for my car. It's not perfect, but it's damn close.
And being a Cadillac tech, OP should’ve had some idea about the 10 speed before purchasing one.
Im happy for the most part? After changing reprogramming the strategy its pretty good. I still have the odd first gear hang from time to time. Could it be better? Absolutely!
That's been my experience as well, for the most part. In Normal mode it was always very smooth, where I couldn't even tell that it shifted half the time. Sport/Sport+/Track had some really hard shifts from 4th to 5th and even 5th to 6th until I had the Ford tune applied. Now that shift is noticeable, but not nearly has hard as it used to be.It's a smart transmission, and adapts to the stupid ways some drive , and can get confused, shift hard 3rd to 4 th , Google 10r80 smart adaptive transmission. For the most part it's been a very good transmission at almost 8 k, early on a funny shift now and again, but was probably confused. I try to be a little more conscientious of what I'm doing and how I'm driving and not drive like all the overly aggressive pin heads in life . There's a time and place for spirited driving out on the open road , where the transmission won't get confused, and that's not in town stop n go traffic . Some will agree , some won't . For some they may need a refresh, as the transmission has learned to many bad habits.

I can't count the amount of times of I've read that comment stated. I really thought that was a fact. My car has 84,000 miles on it. I had the trans rebuilt at 70,000 after doing a FBO build. I used the Suncoast Stage 2 rebuild kit. The Circle D Converter makes it feel like a completely different transmission. My car drives better when I drive it like a sports car. When I drive it like a Caddy or Town car it drives confused. As long as I drive it like a sports car it drives flawlessly! Oh and thats the way it's been since I bought it brand new. The soft driving makes the 10 speed drive wonky. Spirited driving makes it perform much better! Just my 2 pennies!
I agree with engineermike the transmission does not adjust to driving styles. That explains why the Ford performance kit works out the box without learning anything. The increase in low end torque really helped the 10R80. Now that I said that, I commute in normal for that stop and go BS. But in sport, on the shift position, I drive it hard. The transmission knows and drives accordingly. The cost of the kit is off set by not having to argue with the stealership.Mike's a Mythbuster!
Mike, do you take yours full boost in 7-10 gears also? I just heard that it could be a problem. Just wondering what your experience is with that. Thx
