I have nothing but the highest praise for Mobil 1 products.
But why not just use the tranny fluid that's recommended by the factory for the product that was designed for it to be used in.

That way if anything goes wrong with your transmission down the road, they can't say you used the wrong fluid.

Oh wait a minute, I just remembered, your car is anything but stock, so your warranty is probably voided anyway.

In that case, enjoy your Mobil 1.
