New, More Durable Transmission Engineering experience and testing with the 1937 transmission proved it to have five to six times the wearing life of other transmissions. For <strong>1938</strong>, a new and even more durable transmission has been designed for the new Sixteen and is used in all Cadillac and <strong>LaSalle</strong> V-8's. New, More Durable Syncro-Mesh Transmission Countershaft diameter has been increased, adding 25 per cent to strength and rigidity and improving gear tooth contact under conditions of extreme loads. Twenty-eight roller bearings are used on each end of the countershaft. The second speed countershaft gear is wider, increasing its durability by 200 per cent. The clutch connection shaft has greater diameter and employs a new cageless type roller bearing which increases this shaft's torque carrying capacity by 48 per cent. All transmission gears, including reverse, are helically cut for silent operation and then finished with an expensive lapping process. All gears are carefully • 74 •
checked individually and then matched into sets by hand. The expert hand, eye and ear of long trained craftsmen check for perfect running quietness in a soundproof room. The low and reverse gear are of the sliding type mounted on helical splines. Second speed gears are in constant mesh for silence. There are no shifter shafts since the new shift control operates through levers. Friction is thereby greatly reduced and shifting is much easier. On the bottom of the transmission housing is a removable plate for service accessibility* The pin type synchronizer, which made shifting so easy and clashless last year, is continued, and has even greater effectiveness by increasing the gripping power of the drums. The drums are now of tough, strong, corrosion-resisting aluminum alloy. Overdrives, fourth speed gears or other automatic gearing devices, used on some cars, are necessary with small engines to improve economy and life. The extra cost owners must pay for these devices offsets any small improvement in economy claimed for them. Cadillac, however, prefers to use large engines sufficiently powerful to pull the car under all conditions, and runs these engines slowly by means of low standard rear axle ratios. Performance, as well as long life and economy, is therefore secured. Transmission complexity is avoided. Speedometer The speedometer drive gear is placed at the rear of the transmission and is driven by a spiral gear from the transmission shaft. This gives a quiet operating gear automatically lubricated at all times. REVISED 12-13-3-7 •75«
