If the torque converter/transmission pump engagement procedure creates any doubts, double-check torque converter mounting once the engine mates to the transmission, but before tightening any bolts. With the engine on the trans, a 3/16-inch gap should exist between the torque converter and flexplate. If not, don't tighten the bellhousing bolts; the pump isn't engaged (likely) or there's a flexplate manufacturing issue (not so likely). Don't fret if it takes a few tries; the best of the pros have reduced a transmission to alloyed rubble in the past.
