Good morning Mike and to all,
Without knowing whether this trans is in a Stocker or a Super Stocker, internal pressure will push out the front pump seal. GM has a retainer for the front seal but you might need to check that the vent for the case isn't blocked or restricted. Depending on who actually built the unit and who's valve body has been installed will determine why the cooler lines are plugged. My McClay unit has a loop, my Leon trans is plugged. You might want to reach out to Mark Yac. that comes on this site, he might be able to give you some guidance. If someone in Mike's area knows of a good builder, maybe you could chime in here and get Mike some help.
Have a Good Day.

Respectfully,
