Look up Nick's Transmissions on YouTube. I just rebuilt my 700r4 last year and did it by watching his teardown/rebuild videos and by reading the trans book you can buy on Amazon.
Nick talks about it in his videos, but there a couple specialty tools you want. Ebay is your friend here. Has a lot of cheap specialty tools for the DIY person that isn't rebuilding for a living. These are the two big ones you need:
Drum spring compressor: https://www.ebay.com/itm/133532389083
Rear clutch spring compressor: https://www.ebay.com/itm/373828280182 (you can make this if you are handy with a welder and save some $)
I know those are US links, but hopefully you can find those items locally as well.
Parts you want to buy new are the forward and reverse sprags (2 pieces), the upgraded 4l60e piston kit with molded in seals, probably a new pump with vane kit, new sunshell, probably a new reverse drum, and new accumulator pistons. Plus seals, steels and frictions.
I ended up buying everything on eBay, but that may not be an option for you.
One big hiccup I ran into in my rebuild was that the book tells you there are different thickness clips to adjust the lash in the reverse drum stack up. That is a lie. At one point that may have been true when these were new, but no one makes anything but the one size now. So if you're trying to reuse your reverse drum like I did and the tolerance ends up being too tight or too loose you can't buy a different thickness ring. I had to buy a new drum to achieve the right tolerance.
I can provide eBay links to everything I bought if you want just for your reference. Let me know.
