Think I'll pick up a gallon of each, the ATF that's in my converter will give enough color to see it on the dip stick. Agree, while the engine is out I will be making the switch to Hy-gard

I tried it once to see if I could get the conv to stall higher... it didnt help mine so I swapped back... but after reading more info I might have used the wrong one

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 have heard for 40 years that B&M Trick Shift is just Type F with blue dye in it.

Hey Monte according to the table, the reg Hygard handles heat better than the lo viscosity one....
Which do you feel would be better in a street /strip application 727 with a decent cooler and with 5K stall ?

Monty JD lists five hydraulic fluids. Which one do you you run? Most use Hy-Guard or the Low Viscocity Hy-Guard. The Low Viscosity is a direct swap for most ATFs, except if you read the standards is MUCH more durable and maintains viscosity better at higher temps and that's what we WANT. I would suggest the low viscosity for anybody wanting to swap. We have run regular Hy-Guard and a lot of guys with Bruno's and Lenco Drives use this. The regular Hy-Guard will generally tighter your converter up about 200-300 on the stall. Thanks Monty.

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.

The one reason I run the type F is the guys
in the trans lab at Chrysler... I had plenty
of friends in there and asked this question
when I started racing... ALL of them said F
so I did From a factory race bulletin.

Question, I talked to rossler a while ago, he told my about the Hyguard, BUT he told me it might slow the car. (He said the engine should make 1500 or more to use the Hyguard) I tried it and did not really see a change. I use type f as per rossler site. I didn't know it was available in diff viscosity. Maybe I should try the lighter one ?
