the way i can tell if my stall convertor went on is that if you take your convertor off and look down in where the shaft is at the front of your tranny you should see a couple of humps that looks like keys that slides on a shaft,and on your convertor shaft two notches on each side,just slide on your convertor to match up notches,you may also have to spin the convertor some but it should slide all the way in.
