LS / 4L80 Transmission leak

[Gordonr1973]

Hi all;

just trying to figure out a mystery here....I replaced the internal harness last year with another.

Since then I've noticed a small leak that looked like it was coming from inside the connector.

Last night I totally cleaned the connector and trans and this is what I found in the morning.

Is there an o-ring or seal on the inside that might be crushed? I don't want to drop the pan again to work on this if it is a common issue but I don't want it leaking all over for the next 10 years either.

Thanks!
