Figures that I have someone interested in buying my truck then this happens...Recently my tranny cooler started leaking and limped my tranny from low fluid. I replaced the cooler, add 3 quarts of fluid. And it still keeps going into limp mode. I was told if it was over full to check the main plug as it might get fluid in it and cause a limp mode. Checked the plug it did have fluid in it. Drained 1 quart out cleaned the plug out, plugged it back in, and it still goes into limp mode after about a minute of acting fine with no codes.P0751 Shift solenoid SS 1 valve performance- stuck off...P0843 Transmission fluid pressure switch 1 circuit high voltage...P0877 transmission fluid pressure switch 4 circuit low voltage It does have a deep pan also. Any other ideas before it goes to the shop?
