PURPOSE:To reduce a burden to a driver by providing a torque converter, a manual selection speed change gear, a two stage type epicyclic speed change gear and a hydraulic control device and by carrying out a multistage speed change of a forward stage without a clutch by selection of a manual shift. CONSTITUTION:In a speed change gear for a car, a torque converter 200, a manual selection speed change gear 100 having not less than two stages for forward and one stage for back, a planetary gear set 30, a hydraulic servo 24 and two-stage type epicyclic speed change gear 300 comprising a multi-plate clutch, etc. are disposed on a common shaft. A hydraulic control device 500 changing-over said epicyclic speed change gear 300 to the intermediate, low and high speed in accordance with selection of manual shift 400 during setting each forward stage of said manual selection speed change gear 100 is disposed on said shaft. Accordingly, multistage speed change in which the forward stage reaches up to twice stage of said manual selection speed change gear 100 can be carried out by selection of said manual shift 400 with no clutch. |
