Cracked drum or pump. That sound serious, is it a major overhal. Are these parts prone to sudden failure. This tranny was working fine on Sat., O/D, Sport, Cruise...freeway and normal street driving. Sunday AM it croaks. Put it in D and rev to about 3K and it catches D and goes for about 100 yards. Then nothing until it cools down. So it's just parked. Never showed any sign of failure before that moment.
