4L80 conversion on 6L80 vechile, no speedo

[Mike@sic]

hey guys as the tittle says, we did a 4l80 conversion on a 2010 camaro (auto). everything works nicely except for the damn speedo. we tried a few different things but cant seem to get it to work.
the trans is using its own stand alone computer so the speed is working on that. anyone run into of this or have any ideas ? thanks

This not an easy swap on an L99, but we have had success in a few builds this year. What stand alone are you using?

We are using the PCS stand alone.
