OK I'm about to do my clutch. So obviously I'm gonna change the clutch and tranny fluids. Now I've learned Clutch fluid is Brake fluid. So I'm curious what you all suggest for all these different fluids?

What do you consider nthe best fluids for the following and where can I find them?

Clutch Fluid?

Brake Fluid?

Tranny Fluid?

Rear Fluid?

Thanks for all your help guys.

Any suggestions? Particularly the clutch and tranny fluids?

Clutch and Brake fluid = NON SYNTHETIC DOT 3 MINERAL BASED. Anything else and you risk eating the seals (at least on the master and slave cylinders). I'm switching to ATE Super Blue DOT 3 for this. Others have tried it and seem to like it.

Rear fluid for the stock 10 bolt you can use something like Redline or Royal Purple 75w-90. I've used Redline before. If you have a Eaton posi, you'll want to double check but they recommend a 80w-90 mineral oil instead. For that you can get it from GM.

I talked with the guys at Thunder Racing. One mentioned that Honda ATF for the transmission fluid is a good one. Hit or miss on full synthetic ATF. Mobil 1 makes a Dextron III approved ATF. Royal Purple makes some too. Just varying opinions on full synthetic vs standard.
