2000 Dodge Neon Tranny Fliud

I have a 2000 dodge neon Automatic trans.  The pan is leaking, so I
plan on dropping the pan and cleaning off the RTV and then of course
adding in the proper amount and type of fluid.

What tranny fluid is needed?  I do not have an owners manual.  In
addition, how much fluid is dropped when I pull it?  Short of
measuring the old fluid, so I can ballpark how much to put back in.

Thank you.
