of 1 00 when the transmission 10 is to be operated in u201c fifth gear u201d the overdrive clutch assembly 24 and the three five brake assembly 28 are applied causing each of the second planetary carrier 60 the first annulus gear 56 and the third annulus gear 72 to rotate and causing the first sun gear 50 to be held stationary as a result the first planetary carrier 52 rotates with the rotationally coupled second sun gear 58 thereby causing the second annulus gear 64 third planetary carrier 68 and the output member 16 to rotate together faster than in fourth gear and in the exemplary embodiment producing an overdrive gear ratio of 0 82 when the transmission 10 is to be operated in u201c sixth gear u201d the overdrive clutch assembly 24 and the two six brake assembly 30 are applied causing the second planetary carrier 60 to rotate and causing the first planetary carrier 52 and the second sun gear 58 to be held stationary as a result the second annulus gear 64 the third planetary carrier 68 and the output member 16 rotate together faster than in fifth gear to produce a further overdrive gear ratio of 0 63 when the transmission 10 is desired to operate in u201c reverse gear u201d the reverse clutch assembly 26 and low reverse brake assembly 32 are applied causing the first sun gear 50 to rotate and each of the first annulus gear 56 the second planetary carrier 62 and the third annulus gear 72 to be held stationary as a result the first sun gear 50 causes the.
