    I've always thought Dextron III, but we'll see what the experts say.

    Dexron fluids were designed for GM transmissions. You can put just about anything in a TH350, including hydraulic oil, but Dexron is the best choice.

    I have a half a dozen of the 350's in the back. I had to go and out all of the dipsticks and remind myself what GM wanted to run back then. Dexron was is what they all say. I and everybody else here do not remember the last time we saw it on the shelf. I have personally felt the need to run Type "F" for it's friction modifiers so the clutch packs would be consistant upon shifting and bands would last a bit longer. Type "F" was a buggar to get for a while, Now I can find it everywhere here.

    What if the "Hokey Pokey" is what it's really all about?

    I use AMSOIL's Super Shift Racing Fluid in my TH350. It's a synthetic Type-F fluid, but is recommended for all high performance / racing transmissions.

    That surprises me. I bet you can't simply dump F on top of Dextron. You probably have to start off with it dry?

    I guess that's one way to make a Chevy tranny better, put FORD parts in it. lol. (I couldn't pass that one up)

    The fundamental difference between Dexron and Type F is the friction modifier additive for the clutches. GM preferred(s) a smoother shift than Ford. Some folks like a firmer feeling shift, so F is more appropriate for that. BTW the Type F spec went out the window almost 20 years ago as supported by Ford. The name Dexron is trademarked by GM and has no letter T in it. Dexron III is generally backward compatible to previous Dexron applications.

    It's much easier to promise someone a "free" ride on the wagon than to urge them to pull it.

    Luck occurs when preparation and opportunity converge.

    I never mixed the two, start dry without a doubt.
