You didn't ask me, but I am answering.What cable did you use for the 6L80 shifter?

I used Dorman 905-612 but I could have used a shorter version as I routed the cable towards the back from the shifter and then back to the transmission shifter. I did modify the shifter arm on the toyota shifter. This is required to get the right distance throw at each gear position.
Most others route the cable forward and then back to the 6l80e in a S configuration. This requires a longer cable and the cable is in a push configuration, rather than a pull configuration.
