I've had several problems with the truck since I bought it 3 months ago. I've fixed almost all of them-abs was activating which was pushing me into traffic nearly causing a wreck so I changed the abs speed sensor and hub assembly. Front suspension was gone so I replaced that; as well as steering parts, brakes, the parking brake doesn't work, fixing it next. Oil sending unit, a/c belt and refrigerant replaced. The problems left are evap emission vent valve solenoid, throttle pedal position sensor, and random/ multiple cylinder misfire sometimes and cylinder 4 misfire other times. In 4x4 when it gets under a load something sounds like it's binding up and it pops but it still works. When I shift into drive or reverse or accelerate from a stop it has a shift feeling in the rear with a thump sound. Sometimes I can push the gas and it won't downshift to speed up when I'm on the hwy but that's probably the tpps. I just want my 4x4 working and my shift thump from a stop to go away. Help. In 4x4 the noise happens in fwd reverse and when turning and worse in 4lo but happens in 4hi and auto but not in 2hi.

My 2014 GMC sierra pressure control solenoid went bad. Took it to knight automotive, inc. , in plattsburgh, NY for repair. After repair I drove home only to be told by bill delord GMC in lebanon, OH - and boercherding GMC in cincinnati, that the entire transmission was destroyed. Knight put my family at risk by improperly repairing my vehicle.
