the speed of the input shaft 79 by the amount of slip present output members 81 and 82 ultimately drive output shafts 85 86 which transmit power to the drivewheels of the vehicle pinions 83 84 drive intermediate gears 87 88 which have intermediate pinions 89 90 mounted on a common shaft therewith pinions 89 90 are driveably engaged with output gears 91 92 which are fixed on the output shafts 85 86 respectively in this arrangement the elements of the bevel gear set are sized to produce a direct drive connection without torque multiplication or speed reduction between shafts 24 and 79 during forward and reverse drive conditions the double reduction gear train driven from the fluid coupling is sized to produce an 8 1 speed reduction between output members 81 82 and output shafts 85 86 in operation when forward drive is selected brake band 73 is applied thereby locking bevel pinions 71 72 to shaft 24 and in this way causing shaft 79 to be driven at the same speed and in the same direction as shaft 24 to produce reverse drive forward brake band 73 is released and reverse brake band 75 is applied to fix bevel pinions 71 72 to the transmission casing at 77 against revolution about the axis of shaft 24 drive is transmitted by shaft 24 to bevel gear 70 then due to the symmetry of the gear arrangement equally to pinions 71 72 and finally to output bevel gear 78 which rotates opposite the direction of shaft 24 in place of the bevel gear set the planetary gear set shown in fig3 can be used as.
