ABSTRACT:
In the present invention, a single cylinder or solenoid, ratchet-action, three speed actuator is used on an in-line shifter which actuator can be controlled by a button, single rpm switch, timer or a multiple number of rpm switches, or timers with a special controller. In-line shifters can control forward or reverse pattern transmissions. The pattern for a three-speed forward shifting transmission is first gear, second gear, third gear, neutral, reverse, and park. The pattern for a three-speed reverse shifting transmission is third gear, second gear, first gear, neutral, reverse, and park. A shifter for a forward pattern transmission must be pushed or pulled in a forward direction to shift to the next higher gear, and a shifter for a reverse pattern transmission must be pushed or pulled in a rearward direction to shift to the next higher gear. The handle of an in-line shifter travels in an arc through these patterns. The present invention includes an arc accommodating ratchet action mechanism with a single cylinder or solenoid that controls an in-line shifter that controls forward gear changes in a drag race vehicle with a forward or reverse pattern three speed transmission.
