Abstract
A solenoid operated actuator mechanism for positioning a shift fork in a double clutch arrangement for use in a transmission includes a pair of solenoid actuators operatively connected to a shaft that is fixed to the shift fork for positioning the shift fork in a neutral position when the solenoid actuators are de-energized and for positioning the shaft and shift fork selectively in a forward or reverse location if one or the other of the solenoids are energized. The invention includes a first embodiment where the shaft is fixed to the shift fork and to one end of a solenoid core element and wherein the forward and reverse solenoid assemblies are located on one side of the shaft; a second embodiment includes a shaft having end portions forming solenoid core elements.
