  • Patent number: 4421215
    Abstract: A park lock interlock control system preventing the shifting of the vehicle transmission in gear positions when the drive train park lock is engaged. A two part interlock system comprises a park lock control including a crossover shaft and a transmission shift lever connected with a plate having a slot. The shaft projecting through the slot is able to rotate, thereby engaging or disengaging the drive train park lock, only when the shift lever is put in a neutral position, thus preventing an accidental transmission engagement in gear when the park lock is actuated.
