Planning to run a Blackstone UOA on my truck's ATF (2011 F150 5.0 with just under 60k). Factory service is 60k severe or 150k normal and I want to see how my normal service vehicle looks at 60k. What red flags should I be looking for?
I would just change the fluid and save the money for an engine oil uoa, remember the lv fluid will look very dirty when you drain it. This is normal for this fluid and has no effect on longevity.
I'm sure Blackstone's comments will cover any potential red flags. Also, post it on BITOG once you get the report and you can get others' feedback on the results.
