I think I've never seen any lubricant's TBN go UP during an interval.
I'll be curious to see whether or not any of our expert posters have to say about that.
Aside from that, it tells a fairly simple story.
Metals go up copper and iron, while lead and aluminimum follow at a slower rate.
Your additives decreased at a noteworthy rate.
Calcium in particular went from 251 to 32, an *87%* drop.
Boron went from 118 to 44, a 68% drop.
Phosphorous went from 323 to 213, a 34% drop.
I wish I could tell you what the increase in metals means, but I don't understand those fully in the context of transmission analysis.
I can tell you that your metal numbers, while I don't know if they're good or bad, are not in the ranges we see for genuinely bad transmissions on the verge of failure. Faint consolation, I know, but we barely get enough ATF UOA on here for even a focused layman to get the big picture.
As far as the additives went, I feel safe saying your calcium was no longer doing much in the way of helping, while the boron was probably not good for that many more miles. The phosphorous is probably still in the game, and whatever function the antimony is fullfilling, it should still be doing it.
I wish I knew more about ATF UOAs.
I assume you changed this?
If someone showed me the numbers you just posted and they belonged to my vehicle, I'd be inclined to sample again in another 15,000 miles after this ATF change. Perhaps your vehicle will start going through its additives slower once the tranny is broken in. Or, perhaps an expert will tell us that the add pack is supposed to sacrifice itself early in the game. Since your TBN actually went up, maybe the calcium is designed to use up quickly and give you boosted TBN numbers.
