[QUOTE="ericmiles, post: 1422828, member: 118906"] Type F had no friction modifers. Dexron (and Mercon and old type A) has friction modifers. Friction modifiers change the shift "firmness" and are specified depending upon the clutch and band friction materials used in the manufacture of the transmission. The original GM Hydramatic had metal plates and used motor oil. In the late 1940's they switched to a fiber friction material and invented a fluid with the correct frictional properties, Type A. The various Dexron formulas are backward compatible to 1949! Also you can see this page and look at the second FAQ question relative to Type F / Dextron [url]http://www.valvoline.com/faqs/system-fluids/automatic-transmission-fluid/[/url] I don't see how it could harm anything. It should lubricate fine. Worse thing I could think of is that the so-called friction modifiers might make it too slippery or coat the plates resulting in clutch slippage??? I use ATF type F just because thats what I started with and it worked...if I had started with Dextron II or III then I would probably say that worked :) [/QUOTE]
