Default 4R70W Pump Seal Removal?

I had to yank my motor out to swap out few things here and there and I pulled the trans as well since it had a leak and while out I removed the converter and it is leaking from the O-Ring on the Pump. I took off the bolts. Is there a trick to taking off the pump??

i believe that two of the holes on pump is just a tad larger and threaded thru the pump. you can put the correct size bolts in there and screw them down and it'll press against the case and push it out. otherwise your only options are finding the special tool, or hooking some good vice grips up to the fins on the pump and pulling/prying them out. one time i had to do the vice grip thing, pointed the trans vertically, tied it to a bench, and hooked the vicegrips to a cherry picker and pulled it out that way. crued but it worked.

did you look to see if some of the holes on the pump are threaded? i'm almost positive 2 of them are.
