Rolling about 5mph, shift trans into neutral. Shove TC lever forward.

 

Not a good rule to follow. Do low to high shifts, pretty much from a stand still, otherwise you can ship a low range gear. Now when going from high to low, yes, you can do a rolling shift to high because of the angle of the gears are more for giving.

 

So I've got "Force it" and "Shove it" I'll try those this weekend to see if I can get it to go.

Eventually, I think I'll just remove the solenoid. Is the easiest access to the solenoid through the inside of the truck through the console?
