If you ever worked in a trans shop you would see that almost every day.
Front seal can go bad, or even pop out.
Pump gasket can leak.
Pump bushing can go, causing the seal to leak.
A cracked converter snout can make it where you need a new pump, gears, bushing, seal and converter.
Not meant to freak you out, as it’s probably just the seal, but it’s a really good idea to pull the pump, install a new bushing and seal, and give the converter a good looking over for bushing surface wear, seal lip groove or cracks.
It’s how the good shops do it.
