ABSTRACT:
A vehicle transmission with an automatic clutch is disclosed in which for gear shifting the clutch is disengaged with the assistance of a vacuum of a source of vacuum, via a control valve having a solenoid actuated clutch release valve and a clutch servo. Disengagement of the clutch is carried out when a gear shift lever is manipulated with an engine accelerator released. Reengagement of the clutch when the vehicle is in motion commences as soon as the gear shift lever is released and/or the accelerator is depressed. A safeguard is provided so that reengagement of the clutch when the vehicle is at a standstill will not commence as long as the gear shift lever is touched.
