A transmission has a hydraulic control device (200) to pressurize actuating members arranged on a rotary shaft (280) through a fluid connection between the stationary hydraulic device and the rotary shaft. The fluid connection consists of coaxial tubular elements (220, 240) with a tubular passage channel between the inner and outer tubular elements. The tubular elements have sealed connections (221, 223, 243, 244) with the rotary shaft and the hydraulic device.
