South Bend SDD-3250 Questions

77k on my truck and it's slipping under load, so it's time. I have it sitting in the garage, just haven't had the time to install it.

I've seen the formula for the new transmission fluid (1 gallon of DelVac 50 + 1 gallon of 5-30 synthetic syncromesh and use only 7 quarts) but what about the clutch master cylinder?

Do I use brake fluid, or is there another "secret recipe" out there for this?



Thanks!

I've tried the recipes and now am using Amsoil 75-90 MTG.
It's the slickest I've found.
The new HD master cylinder is sealed.
