What are you using in your race torque flites for transmission fluid? Do any of you guys like synthetics? Thanks.

8.81, 158.56 best so far.

Type F in everything. Never tried synthetic.

Same here.Type F.

The synthetics are almost impossible to read. Cope told me Dextron only!

I've been using Amsoil Super Shift or years. Synthetics are more resistant to the heat generated, particularly from high stall converters, and Super Shift has Type F properties for firmer shifts and minimized slippage. My 904's have held up very well with minimal wear turning 1.48-1.51 60' times in a 3,540+ lb car yanking the wheels on every run. I also use their Synthetic Universal Transmission Fluid in my 2004.5 Dodge diesel truck.

Amsoil source and info.

Info on the Super Shift is near the bottom of the page.

Another vote here for type F.

I think that a syn type would be toooo slippery ...and not allow the clutches and bands apply firmly.

what about B&M trick shift

What makes any oil "more slippery" is friction modifiers like moly. A synthetic oil with no friction modifiers will be the same as a dino oil with no friction modifiers. Best part about synthetics is they handle heat better and don't shear.
If you change your trans fluid a lot it's probably not needed.

Some good info guys!

Everyone has their ... and that is cool.

But how many people have had to change their ATF because it "wears out", is "toasted" or becomes contaminated like engine oil does ?

Not a whole lot I would imagine.

Just my
I have run type f for a long time, but as the car got faster, it didn't allow for very long life of my non rollerized parts. With the addition of a transbrake, the lack of lubrication to thrust surfaces really started to show. Now that everything is fully rollerized, it lives well.
For my $$, stay with dexron for anything that isn't fully rollerized, and if you have a high torque application, use the best fluid (syn)to help with clutch lockup and overheating protection.

I've always run Type F except for one quart of Dex added in. Been doing this for 30 years because an old Chrysler Trans engineer turned racer told me that there was a particular additive in Dextron not present in type F that kept the seals at the proper swell, so as long as you had some Dex in the pan you're ok....if you run 100% F you may have issues.

Synthetic is a real misnomer, it infers that the oils are derived from something other than petroleum bases stocks....more acurately a synthetic is really a conventional base oil that has been "cherry picked".... the molecules are much more tightly screened and more uniform in desireable heat tolerent and sufactant properties, in conventional oils it's really the lower more random "acceptable" chains that break down first and weaken/ contaminate the whole batch, you can think of Synthetic as made up of more of an "all star" team of molecules with like type/desireable properties. To my way of thinking Synthetic is "blueprinted" oil...

I can see in racing apps (where HEAT is the #1 killer) that a synthetic would be "added insurance" for bracket racing.

But if you're running a race tranny built and backed by a specialist , you're ALWAYS best to follow his recommendations TO THE LETTER.

Tranny fluid temps (too high or too low) can be a real consistency killer at the track. Back when I used to race I always ran an external cooler with a gauge that I could hit with a water sprayer in the pits and removed the inspection cover so I could cool the Vert. on the real hot days...I'm still suprised how many bracket racers still run off the radiator cooler!!
