    Vehicle:
    2010 Dbl 5.7 145k bought it 7/21 for 18k
    Color mismatched LEER canopy, cheap running boards, LED reverse lights so nobody can stand behind and direct me
    So today I started the truck and got the cel, slip lights on and the 4lo flashing which on the chart says transfer case failure, wiring harness and ecu replaced. Indeed I can't seem to shift into 4 lo from 4 hi which works fine. Could this problem be anything from the switch on down to the hardware? I am planning on changing the fluids in the "diffs and transfer case?" this week. Could rats have eaten the harness to cause this, dang rats causing all types of problems here. Is it ok to drive unfixed for now as I troubleshoot? Tow a trailer around town? Thanks
    Oh yeah code p033d -No description (iso/sae controlled code (core DTC)- not too helpful imo
