The precedent states the factory must prove the product failure was a result of the "failure of the aftermarket fluid". Redline, Amzoil have a warranty that will legally pursue the factory for failure to stand by the warranty for use of their product. The courts found conflict of interest with these factory restrictions. The simple fact is you won't have a transmission failure or an engine failure due to the use of these highly reputable aftermarket fluids. If you were to have an engine or transmission failure, be sure to drain several oz. of the fluid into a clean container. Then its off to court. If the factory learns you have a fluid sample they fold up and fix it since they've already lost in court. Amzoil Universal ATF lowers the operating temp by 50% over all competitors. Heat kills transmission. ie racing and towing
Okay, but I think you missed something very important in my post, or I was not being clear enough! I did not say anything about whether using any additives may or may not cause problems ... my words were intended to ask people to make sure that the base ATF used is Fluid J, rather than any of the more commonly available "older" ATF formulations (from any source really, including Nissan/Infiniti). This is a requirement of the new transmission internals to ensure longer life.
Then, whether you choose to add Redline or Amsoil or whatever, to the Fluid J ATF and believe that it helps you, is purely your own personal choice! And, I make no observations about that, since I have no personal experience with those additives. I have no idea whether these additives help the new transmission or not!
BTW, as a side bar comment, if you have the time and money (to pay lawyers) to fight with Nissan/Infiniti after using something other than Fluid J as the base ATF, and your car sits unused due to a transmission failure, then great! Go For It!
Personally, knowing that the new formulation needed (independent of any additive issue) for the new Infiniti transmission is different; knowing that the new transmission is considerably more complex than anything that Nissan and Infiniti has done before, I'd rather pay the few extra bucks for Fluid J and do it right.
And, yes, as I mentioned earlier, there are now a few non Nissan/Infiniti sources that claim to be Fluid J compliant ... whether they meet the spec or not, I do not know. Again, I do not have any personal experience or results to prove either way ... hence, I plan not to use them myself.
Now, if these are not additives, i.e., they are complete ATF fluids from these sources, that you are talking about, then I am not sure what to say to your points. How about contacting Redline or Amsoil and see what they have to say about Fluid J compatiblity first?
As an aside, would you have the same argument if you put a non-API certified engine oil into your car and the engine fails? That is an even more expensive failure mechanism! What might the courts do in a situation where a specific oil certification is required (independent of any source issue) and the car owner fails to use the correct oil?
How about using a tire whose load index is well below what is needed for the weight of the car? And, you have a catastrophic tire failure at speed? Whose responsibility is that?
My point is that using something that does not meet the baseline standard required by the manufacturer, is probably not a product liability or lack-of-warranty issue that the courts will uphold. At least, that is what I believe!
