What ATF you guys recommend?  This is a C4 with a 3800 stall that will be driven to the racetrack only.

Thanks for your comments.

I use the universal tractor fluid(wet brake type) mixed with a couple quarts of Type F. John Deere Hyguard or equivalent. Some are offered in both high and low viscosity's, but either will work.

Think of it as Type F on steroids. It doesn't have any of the friction modifiers to make your transmission shift smooth(slip!). Its also what was recommended  by my trans guy and converter company.

i noticed that when i switched from dextron to hy-tran ultra that the trans shifted much harder when i was full throttle. it runs cooler too, lenny suggested i use it to keep my temps down

Thanks for all the info guys.   I only drive the car to the racetrack and back, however temps is a concern during the summer with a 3800 stall and 4.10s.

The ATF with steroids sounds good.

For you guys running the Deere fluid, what's the life span on that stuff? Would you change it the same as you would type F or does it need more frequent attention?

Are there any modifications to the trans that need to be taken into account when you do this?

Sorry for bringing back and old post but I was about to start an entirely new thread w/ the same basic question.

I'm about to drop the pan and put a manual valve body w/ a brake in my C4 so now would be the time for me to figure out what juice to put in it.

Thanks

FWIW, i use the case hy-tran because it was local to me and it was recommended by Lenny to "tighten" my converter and drop the temps down as well. as far as changing it more frequently, i have done 1 change after the trans was rebuilt by PA and they said no need to change more frequently than type F or Dextron. i change it with every motor oil change.

I would run the Amzoil 20 weight compressor oil. This is what I run and recomend my customers to run. The Hygaurd oil will tighten up the converter about 200 to 300 rpm. This has been my experience with it , but is good stuff .

1- I look at the condition (and smell) of the fluid, same as any other. I normally break something or make changes before the fluid goes bad.

2- Hy Guard is avaliable in 2 viscositys. If you use the thicker one, be sure to use a screen type filter.

I have also heard good things about the compressor oil, but have never used it. Its true that the thicker Hy Guard will tighten the converter up (currently using it), but I hear the thinner fluid doesn't. I'm going to find out shortly.

From the information I have found, Trick Shift is nothing more than a high quality Type F. It just has blue dye instead of red.

Yes it is true that the Hygaurd will tighten up the converter. Good Luck!
