When I saw an RO print off with this description today, I thought the service writers were just coming up with their own descriptions again, but nope, this is straight from the horse's mouth...

#17249: Service Update - Chuggle Drive Quality - (Jul 17, 2017)

Chevrolet Silverado LD 2017 L83/MYC
GMC Sierra LD 2017 L83/MYC

Condition
Incidental engine combustion events, can occur at certain temperature, loading conditions and throttle positions. When limited or zero torque converter slip is commanded during these events a “chuggle” sensation may occur.

Correction
Reprogram the transmission control module.




Not sure what exactly a "chuggle sensation" is.

Just another word for "shudder"

"Shudder" problems occurring at torque converter "lock-up" have been going on for 30+ years.
 
The term 'chuggle' is so absurd it reeks of something that emanates from under the closed door of a corporate board meeting in progress.
