"When I suggested testing Type F the response was disinterest because the car went down the road"

Maybe that IS a good reason not to switch to F. Perhaps some fear that the cure for "chatter" (groan?) would cause problems far worse than just an annoyance.

Again, the real problem we are faced with here is how does one determine the kind of materials CURRENTLY in ANY tranmission in order to choose the correct fluid??? Especialy in view of the fact that we are buying MODERN produced fluids.

For all we know, any trans of unknown history may have had a variety of differnt fluids installed over the years thus changing the friction materials characteristics.
