Auto Transmission Leak

[Branderrp]

So after recently changing the fluid, filter and pan gasket I've noticed a leak but it appears to not be the result of the pan as I've ran my fingers slightly above where the pan meets and felt fluid

It appears to from above through those connections. The second picture is just above the transmission

I'm not too sure if this issue was there before changing the fluid etc.

Anyone have an idea what that could be?

Could you have spilled some when filling it up?

I'm starting to think it could be a spill
I may leave it for a few days to see how it goes (the rate of leak it's very low)

Do you think I should look out for anything in particular?
