Easiest 727/904 rebuild thread...

Well it took about an hour to get the transmission apart and in subsections. But I'll ask this one is a bust it's pretty much all paperweight...
I'll have to start again with a better transmission. I did expect to have to replace most of the guts with another transmission that I have it was not expecting the actual big block outer housing could be damaged as well. Also I was hoping the tail shaft was going to be usable but it looks like that is rusted beyond usability...
Looks like I'll get another one and try again...
Also you can see where I stuck with screwdriver inside there once the valve body was off. I took out the front pump bolts in from behind tapped it with a screwdriver on the sides and on the top real lightly till it popped out. This avoids having all the pullers and all that and I even posted a picture of the back side of it after it came out you can see the little scratches at the scrubber put in it but no real damage I'm sure this won't be seen when you cross the mirrors up Eric jackson lol...

I’m surprised you didn’t see my posts in some other thread(s) about making cheap slide hammers to pull the pump in a more proper fashion. Whatever works ultimately. This is the only way I roll when pulling the pump. As long as one has long *** bolts you could also use anything heavy that has a hole in it for the sliding weight. Anyway, here’s my setup, guaranteed to not give some here heart palpitations, send them into cardiac arrest....seizures, blow a gasket etc.

find 3/8-16 bolts (8” length shown) some washers, and use two of the biggest sockets you have (1-1/4” impact shown) and assemble as shown. Thread into the threaded pump holes (9 and 3) and violà! Instant slide hammers.
Long carriage bolts would work as well, might be cheaper that what I’ve shown.
