Transmission case part identification

[Gatorbait]

2001 ranger 4.0 4x4 off road special.
Trans is dumping fluid from the front round ,(looks like a housing) with a retainer clip holding them in the front one ,the retainer clip is about half off and fluid comes out fast than I can fill it when running. I can fill it up and still goes in gear drives fine but I don't want to run it dry on fluid.
I need to know what those 2 round units are and how to repair or replace without dropping trans

the band servos the front one in the overdrive the rear one is the interment. there's a tool to get them out not needed to replace them but helps a lot.

they come in different sizes too. there's a two litter code on them like AA, AB, or ZA there's more codes. you can read them while the covers are in the transmission may have to remove the cat.
