I did a 3x3 transmission fluid change this weekend and when I pulled off the plastic shroud, I noticed a lot of oil, dirt etc inside the shroud and a lot of fluid around the tranmission. I've seen some talk about a seal leak or leak from another part of the tranny but I wouldn't know where this leak is coming form. What do you think?

 

pix didn't come over the first time

 

Trace it from top down. Potential rear main seal, that looks like oil, not tranny fluid. Check your PCV valve
