65 and 66 pumps used an o-ring seal. All later versions used a gasket seal. Using the wrong type can result in leaks.

70 to 81 all directly interchange. Only difference is sealing ring width.

OP. No specialist tools needed. It is possible, though unlikely, that your pump is ok. Check it out before you replace it.

Also check the converter snout. Sometimes it can get damaged in situations like this. Check your bell for cracks, especially around your motor bolts.

If your input shaft does not slip out easily, you could have damaged your forward drum.
