ATI Trans Fluid

FSA1673 · 06-24-2019, 11:49 AM

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.

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

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.
