I started off driving one day a few weeks back and came to a stop and went to take off and truck was starting off in 2nd gear I scanned it and came up with the code P2769. Torque converter circuit low, so I replaced the governor pressure solenoid and the transducer and the truck did fine for about a week. Then it did it again and now it's stuck in limp mode. I pulled the sub harness and found one broke wire fixed it and put it back in but still stuck in limp mode. If I clear the code it comes right back when I start the truck. Any ideas?
