Few little issues need some guidance on.

A lot of mopar automatic transmissions leak at the front seal or vent area. Try running the fluid level down at the add mark on the stick about a pint low. Then they don't leak out so much when the converter drains back when sitting.

Remember to check your auto trans fluid idling in neutral warmed up.

Make sure the dip stick tube is sealed to the case with the proper O- Ring and I use black form-a-gasket sealer on them too. Lots of trannys leak here too and run down.

If it is pouring out trans fluid then you are going to have to put in a front trans seal, check the neck on the converter seal surface, check the front pump bearing sleeve that the converter slides into.
