I don't know if it's an automotive thing or what, but yes, Higher Gear Ratios have Lower (smaller) Numbers. My assumption is that it has something do to with tranmission nomenclature - i.e. Low Gear is a bigger gear ratio (number) than high gear. Although Low Gear is also called First Gear and High Gear is called Fifth gear at least in our case). . Now I'm confused! In most magazine articles you read about such things, authors usually make clever statements like "you should put in a lower (higher numerical) ratio differential gear for quicker off-the line acceleration". Now that that is explained, do you really have a source for a lower (higher numerical) ratio ring and pinion set that will fit this transmission, in the reversed mode used in the DMC? (And yes, I understand that the pinion gear is the entire countershaft too!).
