GMC 4wd service light on
I went to Albuquerque this weekend and my Yukon shifted into 4 Low by itself while going 70 on the highway. Then when going 30 it did it again and then didn't show any lights on teh 2wd, auto, or 4 High buttons and when I tried to reset them by turning off the car it still didn't work. It took shiftin up from its lowest gear to Drive for it to change. we have had the transmission checked, the fluids, and the differential. Does anyone have any ideas?
AndyGMC, could you direct message me with where you had the service performed at or who it was by? Thank you for the information.
