727 No forward or reverse

Another update after further examination:

I see that actually rear clutch was fine apart for cracked plastic shim(still in the right place). I think it was installed like this. Steels and frictions in it were fine, not overheated, nor worn out. The only problem I found here were piston seals. They were so loose that piston was falling out of place freely.
After putting new seals its holding in place.
I will put this part of trans together after I get new shim.

I did detailed check on the pump. The case seems really fine, there were visible marks from rings in it but they are gone after some 2000 grid sand paper cleaning. There is no apparent damage to where the gears were, I see nothing there on the stator and case side. The old gears have more clearance. They move more freely than new ones that seem to have nice fit. I put the pump on the converter to see if there is any binding. Pump seems to work very smooth and nice. I will give it a shot.

The biggest problem was with front cluch assembly.
Here steels were bent from heat and frictions were totally worn out to the point where steel was s showing on like 30% of the friction surface. Also piston had really worn out seals, it fell out when positioned piston down.
There are 5 frictions in it. I set the clearance to 0,05", is that OK or too little?
I planned to set the clearace in rear cluctch assembly to about 0.03", is that ok?

Please let me know where should I check other celarance.

Thanks for the help. I hope to test the trans after rebiuld this weekend.
