TransGo TF3- tie back or run cable

hey guys just finished up rebuilding my 727, with an all new Frank Lupo 4200 stall convertor and installed a tf3 full manual from transgo. Now I know you can either run a kickdown cable and adjust for the pressure or just tie the lever back. What would you do?
This is a street/strip car Just driven on cruises or a local meetup.
Im a little behind I guess ..So what does the TF 3 do in order not to use the lever for shifting.
