A two-speed planetary change gear mechanism 28 is added to a basic eight-speed change gear mechanism to provide a 16-speed transmission, the planetary transmission 28 including a manually operated forward/reverse gear mechanism. The two-speed mechanism is mounted within the housing 16 of the eight-speed mechanism. The forward/reverse mechanism includes a shift coupler 84 engageable with gears 80, 82 mounted about a shaft 78 which is coaxial with the upper shaft 30 of the eight-speed mechanism. The input gear 86 which is driven by the forward/reverse gears 80, 82 is mounted on the second shaft 38. The two-speed planetary gear set 96 is coupled on its input side to input shaft 98 and on its output side to shaft 78. |
