Abstract
A manual transmission for a motor vehicle includes an input shaft; a counter shaft constantly torque-transmittingly coupled to the input shaft and carrying driven gears; a main shaft carrying forward driven gears mounted for free rotation and being in a constant meshing relationship with respective driven gears; and a reverse shaft on which a reverse idler gear and a reverse driven gear are axially fixed. The reverse idler gear and the reverse driven gear are in continuous driving connection with the counter shaft and the main shaft, respectively. A reverse gear selector includes a sleeve axially slidably mounted on the reverse shaft between the reverse idler gear and the reverse driven gear. A locking mechanism is provided on the sleeve, the reverse idler gear and the reverse driven gear for torque-transmittingly coupling the reverse idler gear to the reverse driven gear or for disengaging the reverse idler gear from the reverse driven gear dependent on the position of the sleeve. A synchronizer is mounted on the reverse shaft for synchronizing rotational speeds of the reverse idler gear and the reverse driven gear prior to allowing the sleeve to assume the engaging first position.
