What I meant by my knock on wood comment was you may have jinxed yourself.
You can take care of any product and if there are manufacturing defects it will still break down. Even when there are no defects, if it is used hard or outright abused, it can and will breakdown at some point. I get to see it all first hand, owners have come in, had all the regular maintenance done and they still end up with blown motors, water pumps failing at will, etc.
The Trans fluid by your description sounds like it is still clean and OK, not burnt, if it was burnt it would have been brownish in color.
