Abstract
A power transmission system having first to third gear pairs, each having an input gear arranged on an input shaft and an output gear arranged on an output shaft. First to third synchromeshes that may disconnect a corresponding one of the first to third gear pairs from either the input or output shaft, or perform a baulking operation for power transmission until the rotation of a corresponding one of the gear pairs and input or out shaft are synchronized, and/or connect a corresponding one of the gear pairs and either the input or output shaft by meshed engagement. When a speed position of the transmission is shifted from an M-th speed to an L-th speed, the third synchromesh moves toward the third gear pair by a predetermined amount without engaging the third gear pair so as to transmit a driving force from the input shaft to the out pout shaft.
