2023 Sierra 1500 5.3......Service Transmission Soon when shifting into reverse or neutral, on the way to dealership stopped to pick up something SERVICE TRANSMISSION NOW, Will Not Shift Soon.
Dealership tech says that it is the shifter assembly and that it is not currently available, looking at weeks to months so they say. Had to cancel a camping trip this weekend and now what else is going to be cancelled.
I am in a rental ( dealer provided ) but not the same.
Will wait a week until I push the panic button.
