My 2012 Sierra is stuck in park, Press the break and I can move the shifter out of the park position but the shifter just freely glides through all the gear positions. The truck just stays in park.
Try following the shift selector cable and guide from the steering column. When (if, Lmmfao) you get to the transmission see if the cable is connected to it's linkage.
