Thanks for clearing that up, Jerry. I have the ax-15 in mine and used Mt-90, but wasn't sure if the newer transmissions liked MTL better. grubnad, if you have any racing shops near you, they should carry it. If you go on Redline's website, you can use their find local dealer feature. I was able to pick up the fluid a few miles up the road from me and saved myself a hefty shipping cost and the wait.
