teconk, I recently had my heated wheel module installed and they said they updated software/firmware for it. They also did the DRL update. They noted some other recall they would be checking which was a brakeline clearance issue on the rear chassis. That was number N222362040 but never showed for me at https://experience.gm.com/ownercenter/recalls.
Reading the transmission Service Update N222383250 summary on the NTSC website it says the applicability is ‘approximately 7 vehicles’.

Parts Man 1,
Thanks for the clarification. Just curious if the NTSB summary of ‘approximately 7 vehicles’ agrees with what you are seeing.
Does a Service Update also have a TSB or are they the same thing?
Thanks as always!!!
