98.6% of the TFs that come in have their problem in the front drums; which will fall out when you remove the pump. Also, it's a newb notion that just the front seal is the culprit. Pump bushing needs to be checked. If this trans was run low for more than a minute, then the converter is probably worn where it rides in the bushing. The only time I saw a TF leak from the front from around the o-ring or gasket was when somebody drilled out a front oil pan bolt hole for a helicoil and went too deep. It broke thru in front of the o-ring.
