PURPOSE:To change into a desired speed change stage directly, and change speed through a neutral condition only in a specified condition by controlling to set both of two counter shaft selection clutches off, and set a transmission device in the neutral condition. CONSTITUTION:Gears 5, 6, 7 for a fifth speed, a third speed, and a first speed as odd number stage transmission gears, and a gear 8 for backward motion are freely rotatably disposed on a first counter shaft 3. Gears 9, 10, 11 for even number stages are freely rotatably disposed on a second counter shaft 4. Counter shaft selection clutches 12, 13 are set to connect/disconnect the first counter shaft 3 and the second counter shaft 4 to/from an input shaft 1 by supply/stop of pressure oil from a pressure oil pump P by a control valve V. The control valve V actuates the desired one of the counter shaft selection clutches 12, 13 by a control signal. |
