Anybody else using this stuff? I've had extremely good luck with my transmission, even with 275+ HP to the wheels & almost 160k miles. I've used this stuff since the first oil change, & always felt like I had less slippage & maybe a little lower stall speed using it. It's thick like STP, and red in color. It's always an adventure trying to get it to go down the dipstick tube, I ususally have to pull the stick, and squirt this stuff in slowly as I slide the stick back in. I don't think I've ever seen it mentioned here.
