i did the flip on the weekend, i have 120k miles on my transmission. it was 82 f outside and i drove 80 mph for 30 miles and the temp stayed at 156. before it was always above 200. when it was above 200 my transmission would not shift until i was at 2500 rpms until it cooled down to 180. now it shifts the same no matter how i drive the truck. should have done this sooner

have you changed the air filter

you have a 3 wire pressure switch on the ac system, if you have no pressure the low pressure side of the switch is open and the high side is closed. when you have to high of pressure the low side open and so does the high side to command the fans on at high speed. you have either s faulty pressure switch or the wiring to the switch . an open circuit on the high pressure side will put the fans on all the time

try replacing the remote battery

no txab is telling you that you need to have the precat sensors hooked up

did you have the maf sensor unplugged, all the codes indicate it maybe unplugged or not plugged in correctly https://testing-public.carmd.com/Tsb/Download/99612/08ee24ee

pedal commander had nothing to do with it, your 8 speed transmission needed the updated fluid to correct the problems you described

take your trailer plug apart and see if that fixes the problem

the front and rear park lights are fed through the trailer marker relay. check all fuses and the relay . here is the wiring diagram silverado headlights.pdf
