Problems just keep piling up. Check engine light went on when i started the truck and was in limp mode. The truck wouldnt go past 1st gear. Service stabilitrak, traction etc message in the DIC. i pulled codes P0700 and U0073 using my torque pro app. i cleared the codes, started the truck up and ran a diagnostic again because DIC was still displaying service stanilitrak etc but check engine light was off. Torque pro app didnt show any codes

I then use OBDLink app that came with my dongle and that revealed U2100 and B1001-46 and a long list of history codes. i cleared all those codes through obdlink and the only one that came back is B1001-46 and the DIC was still showing the same message. i put the truck in gear and the truck started to drive normal to get to where i was going. 30 minutes later i come back and the truck starts fine and no service lights are active, wth?

is it safe to assume that i have some kind of electrical gremlin causing these faults? The transmission feels fine so i really hope it isnt an indication that its going out

One thing I would probably do if it was my truck is go around and methodically check all the grounds, cleaning and checking all the crimps, re-torquing all the connections, etc.
