My 14' was overheating to 260, felt a knock when slowing down coming out of 2nd. I pulled over and towed it to the house. Code p0777 control pressure solenoid b stuck on. So i changed the Techm and valvebody, had it programmed. Now it wont go in reverse, forward works but its a bit sluggish. When programmed the tech said the tcm seemed to be working and responding correctly. Maybe a bad valve body? Update: I was missing one of the valve body to pump seals. Truck is up and running. I am running between 201-203 while driving in town. 190 on the highway. At idle it crept to 216 but it maintained that. Still going to keep an eye on the temp.
