Blackstone Laboratories Transmission Oil Analysis report

bguild · Mar 12, 2023

I promised I would send in the Blackstone Labs transmission fluid report from my recent fluid swap. This is a 2020 ST with 41,500 miles.

Note the comments. Trans Fluid overly oxidized. High aluminum and nickle. They are saying it was good I changed it.

Kind of makes you wonder a lot about keeping the fluid in there for 100k or more.

Would love to see a few more people pony up the $45 for ATF w TAN acidity analysis. Would give us a good baseline on what is healthy for these vehicles.

I plan on doing my 2020 at 30,000 miles, so will let you know. Its at 25k right now. Its been tuned from Day 1 and driven hard so will be interesting to see what we find.

You can check out the other blackstone thread for my engine oil dips if you need a baseline for that.

What did you replace the stock trans oil with?

bguild, have you noticed any shifting improvement with the trans fluid flush?

bguild · Jul 3, 2023

Huge improvement!! I was about a quart low, and as you saw the fluid was real bad.

Was it a full fluid flush? I asked my local dealer about it and they told me its not something they are willing to do.

Not a "full" flush as a mechanic would define it. I had mine done at Ford and they use the fluid exchange machine. Sadly this doesn't get all the fluid out of areas like the converter. But still, good move to have done it at 40k (dont trust me, trust Blackstone!), and now "newish" fresh fluid at the proper level in there.

I don't blame Ford for not wanting to do it. If you peep the service manual the fluid, they claim, is basically "lifetime" or 150K miles.

But, in practice, people are losing transmissions at less than 50k due to low fluid, bad fluid, etc.

This car needs new trans fluid every 40k miles MAX. My non ASE mechanic-based 2 cents based on lots of reading.
