I have a 1996 c3500 dually with 5.7/4l80e I have code “p1870 transmission component slipping” which causes the trans to go into limp mode and I lose OD and tcc lockup I have replaced the valve body with all solenoids I have replaced input and output speed sensors and even torque converter with no change not sure where to go from here truck seems to drive fine until it throws the code although tcc slip speed is all over the place not sure what is okay as far as slip speed, also when it throws the code I can shut the truck off for 2-3 mins fire or back up and it drives fine until code comes back. I’m at my wits end with this thing any input is appreciated
