I swear by the 3qt drain and fill for all Honda's, once per year. Its a little over kill for 4 bangers, but its spot on for all trans paired to a Honda V6.

Lots of hwy miles or 50/50? Looks excellent.
City/Highway miles are very much 50/50.
You should get TAN for ATF. But looks good.
I do the 3x3 quart Honda flush every 50,000

I think they got the phosphorus and zinc switched.
Ask them to clarify.

Maybe...
The few [censored] analyses I've seen of Honda's 'new' DW-1 show just a tiny bit of phos, and very roughly 350 ppm zinc. I'll have an analysis of some DW-1 later today or tomorrow from a local lab, so I can add that to the discussion if it's useful.

A VOA of the current fluid is always useful in order to obtain a baseline of the fluid for comparison to the UOA.

Yep you are correct bulwnkl.
I just found a VOA of Z-1 and the zinc was 380, phos was 2, just the opposite of Chrysler and GM fluids.
Did the OP ever identify the fluid as to whether it was Z-1 or DW-1?

Hmmm. I would think BL, BLS, or BSL would be innocuous.

Here's the analysis I referred to, above:
Ridgeline ATF UOA (DW-1)
That's a UOA, not a VOA, but it's a pretty low-miles one. 0 Phos showing, and 379 ppm Zinc.
