Bob, yes I am sure that manufacturers know what is best for their transmissions, but I like RESULTS, and I also am a disobediant little bastard and am not afraid of experimentation. A 30 to 40% mix of this product into the factory recommended
synthetic oil doesn't faze me at all. If it blows up, I'll replace it. But I know it won't because of the way it's behaving. It's a personal experience type of thing. It may be thick out of the bottle, but remember. It is being mixed with the rest of the
oil in the tranny. It really thins out and elasticises the whole batch. I wish you could try it out, but that would go against manufacturer dogma though. Sorry.

Cheers.
