I have done all the above to no avail for almost an hour! New cables. I have frayed the ends and cut them off to make a fresh start multiple times. I am worried that I will end up with a cable that is threaded thru the shifter but is too short for the run needed.

If no other suggestions pop up, I will warm up the solder gun and give that a try. I like the way the Sram shifters work but there ought to be a better way to replace the cable.
