Some of the big horsepower turbo cars will smoke the regular trans fluid in one pass and some guys used to change it every pass. The Hy-Guard is VERY resistant to heat.
Only bad thing, is that it's hard to see on the stick. Easily fixed by adding some color dye. I won't say who, but will say that SEVERAL of the trick "race fluids" are simply Hy-Guard with dye. How do I know? Because I have seen them pump it from 55 gal drums into their bottles........LOL!!!
I recently bought a converter from PTC, so at the same time I bought their Trans fluid to put in my fresh build 727. Their fluid appears to be some type of hyd fluid also.
