Torque converter crack

Pump could be ok , need to replace convertor, bushing, and front area gasket and o'ring. Factory 904 conv. Hubs thin down on inside just below notches and this causes a weak area in hub, this is one of the most common failures. Aftermarket hubs maintain thickness the full depth of hub and don't often fail.
Do you have a local trans shop near you?
If so pull pump and carry it in to them they should be able to replace bushing and seal and reassemble pump for you for a reasonable price including parts should be less than $50 .oo
DON'T try to reassemble it and run it or you will pay out big-time when it fails.
I have seen a broken hub lock up a good engine when it fails!!
