ATI Trans Fluid
 

Anyone ever switch between the Super F and the Max Duty Super F and see a difference in stall rpm or % slippage. Looking to tighten things up a bit on the converter.

I would also be interested making converter a little tighter. I think trans fluid comes in different viscosity and seeing if anyone has any experience in this. Thanks Jeff

Obviously, any info you gather here (from racers) will be helpful, but I would call ATI and ask them what they've heard from customer/users, and based on that, what they would expect you to see.

Try some Mobil 404 hydraulic oil.

Re: ATI Trans Fluid
 

It will tighten up the converter but not a set amount. Every combination will be a little different.

Re: ATI Trans Fluid
 

Thanks Marty that is exactly what I was looking for.

The kinematic viscosity of the Max Duty is similar to heavier hydraulic fluids such as John Deere Hy-Gard and Allison Transynd. Most regular trans fluids regardless of brand have similar kinematic viscosity. I imagine it depends on weight, rpm, and torque on what the converter will see.

Re: ATI Trans Fluid
 

Also what happens to different fluids at different temperatures.

Re: ATI Trans Fluid
 

Most manufactures post their kinematic viscosity at 40 and 100 degrees so that you can compare them.

Re: ATI Trans Fluid
 

Torco also offers low and high viscosity ATF as well.

If you do plan on trying the heavier oils, make sure you use a screen type filter, not fabric type
