It likely does not. The previous zinc could of been from the previous factory fill.
It is unlikely we will ever know because no UOA was done on the factory fill that was ran
for 23,000 miles longer than factory recommendations did not help matters.
But below is UOA's of DEX III that have higher zinc levels than Maxlife VOA's.

My feeling is that Oil Changer should have opened his original thread to further complain with a link to this thread.
But, since the cat is already out of the bag, here is one problem I have had with Valvoline's response.
If indeed Valvoline's response was as Oil Changer had repeated (and I have no reason to question it), then Valvoline's response was in error.
Here is why:
One of the anti-oxidants that the ATF Performance Improvement (PI or additive) package contains is a small amount of ZDDP or other zinc ester which "yields" a zinc level of approx. 3ppm to 10ppm of the element zinc in typical, modern ATFs.
Here is a suggested response I think Valvoline should have given(Valvoline are you listening?):
"We have analyzed the ATF in said failed transmission and found the zinc level is not commensurate with our additive levels, which leads us to believe the fluid was somehow contaminated. Therefore, we do not believe that MaxLife was the root cause of the failed transmission. We support our stand that MaxLife is appropriate for this transmission."
I suspect the person who gave the ORIGINAL response was sent through another class on ATF lubricants.
An analysis of the oil from an independent company such as BlackStone would have been helpful.
In addition, a written statement from an ASE mechanic on his findings would have been helpful as well.
Much depends on how you approach a company in your communications with them. I know this from experience when I had my blending company. I had to deny two warranty claims for one of my MTLs because it was obvious that the operator had either added an OTC additive, or the tranny had an internal failure mode. In these cases, I had the fluid sent through an FTIR and parts sent to a metallurgical lab. In one case, it was obvious the operator wanted my company to pay fro an abused transmission.
I.E., before you go to a company with a complaint, have your fluid analyzed and get a statement from a mechanic on his findings.
Be courteous in your communications and if the outcome is not to your liking, your only recourse is SCC.
It is not a good idea to go on the Internet and bash a product as the manf. has a recourse to take you to court as well.
