Over the years it has been very common to use ATF as a cleaner in engine oil. It did work. I've seen lifter noise go away many times with a pint of ATF added to the engine oil.
Today, the oil is better and there are better additives so I would avoid it. If I discovered some ATF in engine oil, I would not be the least bit worried. I would use it. I just would not make a habbit of it.
