    Anyone ever have the manual functions not work and pressing the haul tow mode nothing happens?

    Probably something in the shifter wiring.

    My thoughts also--maybe ran through some high pockets of snow lately--snagged the harness?

    I'll have to check that because there was so much impacted snow and ice between that plate under the tranny and the tranny itself....We havent been over 32 in like 40 days or something like that?? ...its finally thawed out being in the greenhouse now...when the suns out it is actually nice and warm and bright to work on this

    I was saying up in the shifter handle. If it were messed up under the truck you would probably get a "Range Shift Inhibited" across the dash

    I agree with nichols. It is somewhat of a common problem especially with plow trucks which the driver moves the shifter a lot more than normal driving. The wire breaks where it enters the steering column from the shifter. Pull back the rubber boot between the two and you might see the faulty wire.

    I have had to do that on trucks before. The shifter goes up and down and up and down and finally the to wires that go to the button break. They are like 22 gauge wires.

    Here is what it looks like off the truck.
