    2014 3500 w/68RFE, P0750... Help Please

    I have a Laramie Longhorn dually mega-cab, 144K miles, that went into limp mode while driving. I had it towed to a shop, code pulled was P0750. I am being told all wiring was checked between the ECM and VB, no trouble found. They replaced the valve body w/new VB assembly, this did not resolve...
