valve body shift kits applications/modifications

[hemi68charger]

Hello All,
Was curious on the complexity/difficult(ness) of performing the modifications of a 727 valve body with a, for example, TransGo TF-1 kit. I'm looking to tackle something like this on a stock 727 valve body. Any videos out there? From the looks of it, the kits are very simple with minimal parts..

Thanks.

One requires some drilling of one passageway in the valve bodies wall. Not to hard to do, but can get messy if screwed up...Other than that, basically can be done if you follow instructions.

This is not a tough task at all. I have done several over the years with no problems. Instructions are clear and results always seemed fine. Be clean and lint free.
