Tahoe 2005, trasmission Leak

[ccv1982]

Hello I have this leak... can you guys help me?

It looks like a seal problem... is not leaking to much couse I cant see nothing in the floor.... The trasmission liquid is king of pink but this one look very oily...

Is your truck 4wd or awd because that could be gear oil out of the transfer case...
