Completely agree.

But I would respectfully point out that consensus implies a large sample, and you are holding your example out as proof to the contrary, in a case where n=1.

I would not expect you to have had a problem after changing your fluid, as more transmission will be fine post fluid change than will fail. But we are discussing the risk of failure, statistically, not whether they will all fail. And on the other side of the coin, you don't know that your transmission wouldn't still be running fine with the original fluid. You spent the money, got no return on that investment, and arguably increased your risk. Is that an investment decision you recommend all should make?
