M6 Fluid Is this normal???

Hi all,

I have a 2002 Z06 with 12k miles that I bought a few years back from the original owner. Dif and trans fluids have never been changed.
So I decided to change them, and was surprised that the fluid from the transmission was dark red, but dirty looking.
Sticking my finger in the drain hole I did not get any "fines" like we see in some differentials or auto trans pans.
Is this normal?
The dif oil was almost clear. the car had original tires when I bought it so I know it was babied and I'm past the point that I run the cars hard.
Trans was quiet, as well as dif.
Hoping the Mobil 1 Synthetic will improve shifting, but that was ok as it was.
I appreciate any feedback.
Pete

I’m planning to drain mine in the next day or so, but at 110,000 miles the history is more mystery. None the less, I’ll pipe up with what I find.

There are 2 large magnets inside the case. Need to disassemble trans to clean those.

Thanks for the reply...
That's probably why there are no fines in the bottom, there stuck to the magnets.
I could see doing that if I was going into the case, but this is just a R & R of the fluid.

Is the darker oil common?

Many comment how the shifting improves after fluid change. Let us know.

I know that everybody has their favorite products, and in my 2001, all it has seen is Red Line oils in the tranny and diff, since the car was about a year old.
