please pick up the book : Torqueflight A-727, Transmission Handbook [How to rebuild or modify Chrysler's A-727 Torqueflight for all applications] by Carl H. Munroe.
it's a great handbook, and does a step by step TF-2 installation with pictures, starting on page 165.
it also details the rebuild process, as well as anything else you may want to learn about this transmission.
well worth the price.

might well be good advice as Trans go's Instructions used to be like walking a drunk duck. Loved the kits, but the instructions should have been written for a Dyson or Shark as they Sucked real well. Maybe they've redone them
I've found Trans Go's instructions very easy. Their tech line is great as well.

It's been quite a few years since I did one, so possibly they have rewritten them. They use to jump all over the place. Start with the valve body, go to the case cup restrictor, back to the valve body, modify the plate, lets do the check balls, Oops, now let's drill one of the channels, back to scratching you backside, WHERE WERE WE ? Oh yeah set the line pressure, back to drilling.
probably not quite that bad but close LOL
