Abstract
A transmission system, including a synchromesh-type transmission, includes an input shaft, a counter gear, an output shaft, an idle gear, a sleeve, a synchromesh mechanism for selecting a predetermined speed-change in response to a synchronizing operation of the sleeve and the idle gear, and a shift actuator for activating the sleeve depending on a shift operation. The transmission system further includes a detecting device for detecting a rotational number changing ratio of the input shaft when a synchronizing operation is performed in accordance with an engaging operation of the sleeve and the idle gear, a controlling device for controlling an operation of the shift actuator depending on an indication from the detecting device, and a converting device for converting an output indicating value to the shift actuator based on characteristics of the shift actuator.
