Trans leaking, seems to be only dripping from the flywheel dust cover.

I drained the pan a couple weeks ago and put in 2.5 quarts fresh fluid
which is amount that I took out. And now it's leaking, about an ounce overnight.

Cannot see any leaks around speedo, dipstick, etc. It's all coming from bottom of dust cover.

This is a 75,000 mile truck (72 350/350) and the trans shifts/drives perfect.

I searched a lot of old threads but couldn't find this exact problem. Any suggestions or ideas appreciated.
