That sounds like what he said...something about the pump...iduno...Everything in my trans is from COAN ,including the converter...and this all took place back in 2002 when he built the trans the first time for me...if that tells you anything.I do know he is a damn good tranny guy. He races a tube chassis beretta with an aluminum 415(or 421 don't remember) sbc 18 deg headed motor. Runs a terminator set up on it.
