After sitting for a few years, now that the car is running and been around the block a few times the pan gasket seems to be leaking. Runs nice, shifts very nice and the fluid smells and looks new. What would ya'll do?

edit: The homemade kickdown rod works great, also! Got a pic here somewhere.....

Perfect and sound advice by toolmanmike, and those reusable rubber gaskets are the ticket so I wouldn't use anything else since one of those.
There is a small cork gasket between the trans mount bracket and trans with 2 big Phillips screws in the metal cover so you might want to give an inspection since they are also cork and may be in the same condition, but other than that if it isn't leaking don't mess with it.

Filter, gasket and fill her back up should be just great.
PS. if you run it for a min just before you pull the pan you won't loose as much fluid.
