connects the sun gear member 42 to the input shaft 17 the braking synchronizer 70 connects the sun gear member 52 to the transmission housing 80 the rotating synchronizer 71 connects the ring gear member 44 to the planet carrier assembly member 56 the sun gear member 42 rotates at the same speed as the input shaft 17 the planet carrier assembly member 46 and the ring gear member 54 rotate at the same speed as the output shaft 19 the ring gear member 44 rotates at the same speed as the planet carrier assembly member 56 the planet carrier assembly member 46 and therefore the output shaft 19 rotates at a speed determined from the speed of the ring gear member 44 the speed of the sun gear member 42 and the ring gear sun gear tooth ratio of the planetary gear set 40 the sun gear member 52 does not rotate the planet carrier assembly member 56 rotates at a speed determined from the speed of the ring gear member 54 and the ring gear sun gear tooth ratio of the planetary gear set 50 the numerical value of the fifth forward speed ratio is determined utilizing the ring gear sun gear tooth ratios of the planetary gear set 40 50 the sixth forward speed ratio is established with the engagement of the input clutch 62 the braking synchronizer 64 and the rotating synchronizer 66 the input clutch 62 connects the sun gear.
