A point that happened to me was mine would leak about the same. I kept seeing a leak at the front seal area as if it came out from where the seal was pressed into the pump. I had the retainer and the seal never pushed fluid onto the converter to fling it onto the inside of the bellhousing. It would not leak on the lift even at full TV pressure. I did as Dave Husek suggested and maxed out TV line and slowly brought the rpms up and still could not get it to leak. I finally found that it was the cooler that would plug and it would spew out. I thought my converter hub had cracked, Vigilante balloon plate weld leaking, pump oring, pump bolts leaking or porous case. Finally found mine by flushing the cooler again and after coming inside to eat and then go out, it popped the lines loose and I finally found out the problem. By-passed the radiator cooler and no more leaks.
