Patgizz,
If it was a cable issue I would have found it during instalation, right? I have put 1,200 miles on it, one day turned the truck off and the next morning she wouldn't down shift out of first. I know I can manually take the TV cable linckage off at the tranny and place it into gear with my hand but I am still not sure what to look for with the cable.
Lost in the sauce, I am dipping into the cool aid and I don't even know the flavor!
