description A transmission system is disclosed for use with a machine. The transmission system may have a first clutch to transfer power in a first direction, a second clutch to transfer power in a second direction, a brake, a sensor to generate a first signal indicative of speed, and an input device to generate a second signal indicative of a desire to shift directions. The transmission system may also have a controller 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 second signal and a target transmission system speed, to selectively increase retarding torque when the error value increases, and to selectively transfer retarding torque to the second directional clutch when a value of the second signal is less than a threshold value.
