ALMOST EVERY MOTOR CAR manufactured in the U.S.A. is fitted with one form or other of automatic transmission system. Such transmission systems are quite complex and the fluid used must meet exacting specifications, which, incidentally, are not all exactly similar for all systems. There is little doubt that we are approaching the same stage in our own car manufacture because, even if we ourselves do not consider it worth paying the extra cost of these refinements, if our overseas customers demand them, we shall have to supply, and indeed are supplying.
