What standard testing method would one use to determine the coefficient of friction of (C.O.F.) of automatic transmission fluids? Guidelines for the Question of the Day: 1. No Piston Cup Lapel Pin will be awarded to the same person within 14 days of a previous award. 2. Please respond with a complete sentence. 3. Please do not post links. If a question arises as to the need for clarification, then sources and links may be requested. 4. Please, no off topic posts.

Let me restate the question: What standard testing method OR methods would one use to determine the coefficient of friction of (C.O.F.) of automatic transmission fluids?

For determining wet clutch behavior of the clutch-fluid combination, a number of tests can be done, The SAE #2 Friction Test is one test method used used for determining COF. Another is the JASO M348 (modified SAE #2 Friction Test) and the JASO M349 Low Velocity Friction Apparatus (LVFA) (Du/Dv) test. Another is the CEC L-11-T-72 COF test using the DZK friction machine. Since Faulken was the only brave soul to submit an answer, we award him with the coveted Piston Cup Lapel Pin. happy
