If yours is the lip style seal,get the seal installation tool. I did have to modify mine slightly with a file to get it to work correctly but they do work. If you get one,you will see what I mean. Really hard to install with no damage without one.
I opened up the transmission and one of the metal rings that is supposed to seal of the passage way so the oil make it to the clutch was broke so I replaced it and it still leaks enough air from around those rings that with 75 psi of air pressure I can spin the clutch pad.
How much pressure should it take for me not to be able to spin the clutch pad?
I checked the seal in the clutch and it seems to be fine
sounds like a leak was causing it. Can't be of too much help at this point in respect to the leak is caused by something and I can only guess what that could be. hopefully you find it, glad we got the problem figured.

Shop air should be enough to do it by hand. If it's still leaking then it either damaged the drum or the ring isn't seating properly still. Did you use metal or Teflon to replace?
You can try liberally applying trans fluid to the hub and into the bore when testing, as the fluid pressure behind the ring actually pushes it out into the seated position which may not be happening with just air. If that doesn't help, remove the ring and insert it square into the bore and make sure it has tension. If it's too loose it may not seat.
