I had a leaky tranny replaced the pan gasket a couple times. It turned out to be a leak in the O ring of the tranny dipstick tube. C6

Yes this is a very common place for our Ford automatics to start leaking. It's called the "selector shaft" (which the kickdown bracket and shift linkage actually hook onto).
There is a seal about 1/2" inside the aluminum casing there, (that seals around the selector shaft). Part #7B498 behind the turn signal switch in this image.
As far as I know there is no way to replace that seal without dropping the pan on the transmission / removing the valve body / then removing the selector shaft and replacing the $5.00 seal. I'd source out a written quote from a local tranny shop on this repair. And don't run the tranny long low on fluid or you'll be sourcing out a rebuild on the transmission! :(

Easy DIY fix. A trans shop will charge at least an hour labor to replace the seal and o ring.

Just reading this after cleaning up the oil leak in front of the complex before the landlady see it :D

In my case, I'm pretty sure the front pump seal on my C6 is getting ready to lay down and die (if someone hasn't already administered the last rites while I wasn't looking). The poor truck sits for such long periods, I'm sure all the seals are hardening up.

1guydude - if it makes you feel any better, at least you won't have to pull the transmission to fix your leak :o
