Abstract
A semi-automatic transmission for a vehicle having a diesel engine is provided which, upon start up of an engine ignition, goes through a warm up stage before the engine begins normal operation. An electronic controller is connected to the engine, a clutch, a gear box, and a signal transmitter. During start up of the engine, the electronic controller cause the signal transmitter to emit a signal which notifies the driver of the vehicle, based upon the position of an ignition key in the ignition lock, to disengage the clutch. Alternatively, during start up of the engine, the electronic controller detects whether the gear box is in a neutral position and whether the clutch is not disengaged. If the gear box is not in the neutral position or if the clutch is not disengaged, the electronic controller causes the signal transmitter to emit a signal which notifies the driver of the vehicle to disengage the clutch.
