I have the 2017 CT6 platinum, my only disappointment with this car is the transmission. I got it used with 20k miles.
I noticed shifting issues when I started to drive it. I was still under warranty for the drivetrain so I had my local dealer
check it out. After a number of iterations, ended up replacing the transmission. As I have researched this this transmission
has issues with design. The poor shifts are usually 1-2. It doesnt do it all the time but more than I would like. I live with it because
i really love the car, 3.0TT, 34 speakers, active suspension, a black on black paint and interior. The 20 inch wheels, I get 30mph on
he highway.
