727 issues... again...

This is what I would do were I in your shoes.
1. Check the fluid right now and verify that it is low, not burned and smells right.
2. If it leaks when you start it and it was verified low, then it's either a cracked converter or a seal issue.
3. If it doesn't leak right away add fluid till it's at the full mark.
4. If it still doesn't leak drive it.
5. If it does leak pull it.
