    its prob the front seal that is in the pump, and seals on the converter.

    or the seal from the pump to the case.

    two different things.

    both mean that your tranny has to come out.

    either one you can fix yourself. i.e. no special tools needed.

    yes the converter and the pump are two different things. the pump is internal, you must pull the pan and remove a few things to remove the pump.

    if the seal is leaking, sometimes the bushing behind it is bad allowing it to leak. you need to remove the pump to replace the bushing. some tranny shops have the $$$$ tool to remove the bushing without pulling the pump, but most do not. you must remove the tranny to replace the seal. when you pull it out, look at the bushing and see if there are any scratches or if the yellowish color is gone, its bad and needs to be replaced. also look at the converter hub to see if that surface is bad. if it is, you need a new converter.
