Abstract
The compound detent mechanism (104) for a manual change gear transmission (10) of the type wherein engagement and disengagement reverse gear is controlled by a first shift rail (58) and engagement and disengagement of the lowest forward speed is controlled by an adjacent second shift rail (56) is provided. Detent mechanism (104) is carried by the shift block assembly (88) associated with the first shift rail and includes a first piston (132) resiliently blocking transverse alignment of a shift element with the contact surfaces (96, 98) associated with the second shift rail (56) associated with the lowest forward speed and a second piston element (114) resiliently blocking shifter element transverse alignment with the contact surfaces (100 and 102) associated with the first shift rail (58) associated with the reverse speed ratio.
