A transmission system (22) is disclosed for use with a machine (10). The transmission system may have a first clutch (34) to transfer power in a first direction, a second clutch (36) to transfer powerin a second direction, a brake (43), a sensor (46) to generate a first signal indicative of speed, and an input device (18) to generate a second signal indicative of a desire to shift directions. Thetransmission system may also have a controller (44) to cause disengagement of the first directional clutch in response to the second signal, and to cause the brake to apply retarding torque. The controller may also be configured to determine an error value based on the first signal and a target transmission system speed, to selectively increase retarding torque when the error value increases, andto selectively transfer retarding torque to the second directional clutch when a value of the second signal is less than a threshold value. 本发明公开了种与机器(10)起使用的传动系统(22)。传动系统可具有用于在第方向上传递动力的第离合器(34)、用于在第二方向上传递动力的第二离合器(36)、制动器(43)、
