I have a 2008 GMC Yukon Denali XL 245,263 Miles on it. It was driven 16k a year and we bought it from a Traveling Nurse so it’s really highway miles when it had 242k on the meter. No real problems But just recently the transmission started struggle when shifting pass 3rd gear. Went to Autozone to get it checked and it had a PO872-00 Code for the Transmission Fluid Pressure Switch 3 Circuit Low Voltage. Any ideas on what should be done?
