Hi Robyn
Yes it is a 1500 with the 700R4
It moves forward just a bit in Neutral,not enough to actually move anywhere. Just enough to give a bit of forward motion like an inch, and doesn't move at all in reverse. It acts like it's working against it's self in reverse as the engine will not rev up with the skinny pedal to the floor.
Chances are it will not get looked at for a while,My Build a Truck project is ahead of it and with spring it is relegated down the list. If i sell my current shop gas station this year it will be a while before i get a replacement shop built and setup.
