<p>Sudden accidental or unintended movement of an automatic transmission into reverse with the engine running is prevented by substituting for the usual unitary control rod a two part arrangement, one being movable by the shift lever and the other being movable by a spring separator from the shift lever but arranged to exert a force only in the direction of a parking pawl and never in the reverse direction against any member connected to the detent plate. Thus it is impossible for a yieldlng cam spring to ever drive the linkage unexpectedly into reverse should a driver carelessly position a shaft lever between its reverse and park positions.</p> |
