Trans-go TF-3 kit question

I'm getting ready to rebuild my trans. (727) for my Cuda and will install a shift kit. I see the Trans-go TF-3 converts to full manual valve body but I can't find anything anywhere that says if it still applies the band in low. Does anybody know?
I don't want something without low gear band apply by the looks of that one picture of the one that exploded.

Thanks, Tracy
