HYDRAMATIC (Standard and Dual Range) FRONT DRUM AND REAR DRUM AND PLANETARY UNIT PLANETARY UNIT TORUS ASSEMBLY REVERSE ASSEMBLY AND EXTENSION HOUSING FRONT SERVO Olt conTROL BoD, MANUAL AND THROTTLE SHAFT This 4-speed Hydramatic was the first truly automatic transmission in general use on an American car. A fluid coupling takes the place of a friction clutch giving smoother engagement and much less maintenance. The gear box has three principal units, The first two have a multiple disc clutch, a drum, a band, and @ planetary gear set. The hydraulic system applies these clutches and bands to produce low and three up shift speeds. The third unit has a cone clutch to hold the intemal gear of the third planetary gear set, thereby causing reverse. A reverse blocker piston prevents shifting into reverse above 10 mph car speed. There is no selecter lever “park” position, but “reverse” when the engine is not running applies the rear band and engages the parking pawl.HYDRAMATIC (Standard and Dual Range) TORUS ASSEMBLY & FRONT PUMP (0-0@ epi CASE, PAN & VALVE BODY . \ 2 preven, 3 GOVERNOR & REAR PUMP PRESSURE REGULATOR f/f Gpdd--« @ FRONT PLANETARY, BAND & CLUTCH 2—togo|_—o r fi a ; * Sa.
