    摘要: A countershaft type power transmission comprises a select shaft operatively connected with a select motor and a shift shaft operatively connected with a shift motor. The select motor and shift motor actuate the select shaft and shift shaft in response to various vehicle operating conditions, including the position of a control lever so as to engage a desired gear within the transmission. Means is provided for temporarily connecting the operative connecton between the shift motor and the shift shaft when the control lever is moved toward and into the reverse position, so that the shift shaft can be manually rotated via a mechanical connection between the control lever and the shift shaft to engage reverse gear.
