Just remember the Benz automatic fluid will always turn black very quickly due to the high graphite contents. That is normal and not an indication of a problem. Did you use the genuine MB fluid? If so, you can check and it's probably black by now. If you did not use the MB fluid, you can start saying goodbye to your tranny.

OK, it looks like crap, but what does it smell like? Smell is a good indicator of the fluid condition as well, sometimes better than looks.
If you want to get a REAL good idea of what's going on, have some of the fluid analyzed, it doesn't cost that much and it can either give you peace of mind, or a heads up on saving up some extra bucks... :D

Yes, I did use MB fluid, the light red color. The old fluid was not runny a bit thick and smells bad.

Smells bad = not good.

Like I said, I would get a sample kit and send it t a lab to get analyzed. I would want to know just what is going on in there……. :dunno:

This looks like one place you can try, and it's less than $25.00 for peace of mind.

Blackstone Laboratories

There are plenty more, just Google oil analysis.

Ive seen a few in the workshop I go to just like that. They tell me its normally what they see.
They just change out, new filter and go until the next change after about 30k or so.
The oil should stay transparent for a while. Any additives on the bands would of leached out by now.

I sent a sample to Blackstone after 35,000 miles

A couple of years ago I sent a sample of ATF from my wife's ML320 at 35,000 miles.
The report came back saying the fluid although dark was still in good condition.
I'd had the fluid changed at the time and I resolved to leave it in until 100,000 miles basd on the Blackstone report. The ML320 is currently at 92K so it shouldn't be too long now.

I changed mine a couple of weeks ago (100k) and found it was black, but the magnet was clean and the fluid had no smell. It shift's fine, so unless you have chunks in the pan you should be ok.
