This would be fairly considered to be cosmetic and not functional damage.
As long as it's not leaking, there is not a failure.
I do realize that your fear is that the damage will morph from cosmetic to functional failure, but that's not warranted in the Wix written limited warranty.
In PFMEA and program developments, there are three things to consider:
- issues; know problems that are happening, are understood and can be fixed
- risks; potential problems that can be well defined, articulated, and described within a time-frame
- worries; emotional feelings or hunches that have no specific evidence of failure nor any timeline to failure
You're worried. That's OK. It's not wrong to have emotions. But it's also not a real failure; the gasket hasn't stopped doing it's job. Even if it did start to leak, it will be a slow drip that you'll discover. It's not like the gasket will have a blow-out and puke all tranny fluid out in 2 minutes, leaving you stranded. After all, this is the part of the system that only has gravity as it's pressure inducer.
Wix does not owe you anything; there is no failure here. If you are upset with that, then try another vendor. But you'd probably get the same response out of Purolator, Bosch, Fram, etc. In fact, why not write/contact some other companies and get their take on this problem? Ask them if they would warrant a product replacement based upon a visual cosmetic defect?
