Perhaps the most important change on Morgan Moss gearboxes were the ratios. There are "low ratio" gearboxes, but they were only used up to July 1936, or gearbox nr. 1217. The high ratio gearbox can be identified by an "HR" suffix after the gearbox number. (Stamped on the top cover, front left hand corner, and also on the side of the case, left top rear corner.) These "high ratio" gearboxes were fitted to Plus 4 chassis numbers 3517, 3529, 3533, 3538, 3541-1 and 3544 onwards, which means, that the +8 also had this box fitted. The ratios were changed simply by increasing the number of teeth on the primary (input) pinion gear from 25 to 28 teeth, and correspondingly reducing the number of teeth on the mating layshaft gear from 39 to 37 teeth. The effect is to make the indirect gears higher and the gears close. Later gearboxes had an oil shield fitted immediately behind the rear mainshaft bearing to prevent oil flooding the speedo drive and oil seals. Also on later gearboxes, the top cover incorporates a reversing light switch.
