Broadly, the present invention is directed to a method for controlling the shifting of a drag race vehicle with a controller for controlling an actuatable shifter assembly. This method includes resetting the controller followed by actuating the controller and launching the vehicle. At a predetermined engine speed value or after a first timed duration based on a predetermined engine speed value, the shifter assembly is actuated for a second timed duration to shift to a next higher gear. Finally, shifter assembly actuation is repeated until all of the gears of the vehicle desired to be shifted have been shifted. Another aspect of the present invention is a controller for controlling the shifting of a drag race vehicle shifter with an actuatable shifter assembly and which is activatable by a first duration timer or an rpm switch based on a predetermined engine speed value. This controller includes a reset for resetting the controller; a second duration timer; setting means for setting the number of forward gears which the vehicle has; and means for causing the activation of the shifter assembly actuator until all of the forward gears of the vehicle desired to be shifted have been shifted.

An improved automatic transmission is disclosed comprising an input shaft, an output shaft and a countershaft with the input shaft rotating the countershaft. A plurality of countershaft gears are secured to the countershaft and are in rotational engagement with a plurality of drive gears rotatably mounted on the output shaft. A plurality of clutches are mounted between the output shaft and the drive gears for transferring rotational power from the input shaft to the output shaft upon engagement of a selected one of the plurality of clutches, respectively.

A device comprising means capable of emitting an electrical signal and means responsive to said signal and adapted to command a change of gear. The means capable of emitting the signal include a light source which can be caused to communicate with a receiver element capable of triggering the electrical signal, and two rotatable shafts, the angular amplitudes of whose rotations depend respectively on engine operating parameters. The two shafts cooperate with means for causing the light emitter and receiver to communicate. Application to the control of an automobile gearbox.
