I'm currently taking a quick look through the owner's manual that was just released and would like to make note of a few things I find interesting.
First, from Page 287:
Relevance: When GM employees of dealerships went to the special test day, there was a big hoo-wah about how the transmission oil change interval was 12,000 km. I didn't think that would be true by any stretch of the imagination. Good to see it was fake news.

Interesting there is a special filter for the transmission fluid that has a more frequent interval for changing.
First, from Page 287:
Transmission Fluid Change
When the CHANGE TRANSMISSION FLUID SOON message displays, change the fluid and filter within the next 1000km (600mi). Failure to change the transmission fluid at required intervals can lead to reduced transmission performance. The transmission fluid must be changed at least every three years and the Fluid Life System must be reset. Your dealer has trained service technicians who will change the fluid and reset the system. If the system is ever reset accidentally, the fluid must be changed at 72,000km (45,000mi) since the last fluid change.

The initial transmission canister filter change must be performed at 12000km (7,500mi), and every 36000km (22,500mi) thereafter. This service can be complex. See your dealer.
