I have convinced myself to change the whole transmission out. As you say, the radial is part of the assembly anyway, and to change only the radial and have a different transmission issue down the road makes no sense. A new assembly should easily get the machine to where it goes out for pasture when the original got it to almost 13K hours.
I started this post convinced it was an electrical problem, finally took the blinders off and saw the light.
Thanks everyone for the help!!
