Changed the fluid today, just a change I did not pull the cover. Having never seen the OEM stuff, does this look like it?
It was very clear, and after probing the drain with my finger I found zero metallic sludge, particles or shinies.

Shined the full port, the teeth I can see look nice. No sharp edges and a nice even grey coloring.
Are there any magnets in there?

The schmutz you see in the pan was leftovers from me not wiping it totally clean.

Your good, actually looks real nice. The hue is from additives whether natural or dyed they end up that hue. I didn't think OEM fluid was so red, but it doesn't surprise me.

Looks like somebody already changed the fluid prior to you,as Redline diff fluid looks like that.
Your 15 will probably call for 75W-140 stick with it.
