I meant to say the on the three-speeds (A131L), the fill on the differential reservoir - it is only filled via the fill port on the side of the differential/transaxle case on the firewall side (like a manual transaxle) - it is not fluid connected to the main transaxle which is filled via the dipstick tube. The transaxle portion holds about 2.5 quarts, the differential will hold about 1.5 quarts.
Different story with the 4-speed autos (A245E) - they are joined together internally - so they share the same reservoir. Fill through the dipstick fill. Holds just about 4 quarts for a drain and refill.
As for the RTV, I agree, won't hurt, but moderation is the key. If you start bolting things up and RTV squeezes out - then that is too much. I personally might smear on a very thin layer on the pan lip to help the gasket "stick" to the pan. Though I've noted that many gasket manufacturers are starting to run a couple of smaller key holes on the pan gasket, usually close to the corners, making RTV unnecessary. They allow you to thread a few bolts up there and hold them in place via friction. That way the gasket won't unfurl as you try and line it up and replace it back on the transaxle.
