Abstract
A manual shift tower has a selector lever pivotally mounted for manipulation by an operator along a path to a plurality of forward drive ratio positions and a reverse ratio position. The tower has a solenoid control bellcrank which is operable to position a pin in the path of the lever to permit removal of the shift lever from the reverse ratio position when the solenoid is in a first position. The bellcrank of the solenoid is also drivingly connected with an ignition cable which is operable to position a stop member for preventing removal of the ignition key until the shift lever is in the reverse ratio position and the ignition is turned to "Off".
Claims1
A shift control assembly comprising:
- a shift tower having a base, and a shift lever pivotally mounted on said base and being selectively movable along a neutral path and ratio paths to a plurality of transmission ratio positions including a reverse position;
- a single solenoid secured with said base and having an output member movable to first and second positions;
- a bellcrank pivotally mounted on said base having a first arm connected with said solenoid output member, a second arm pivotally connected with a pin and a third arm connected with an ignition cable, said pin being slidably disposed in said base for movement into and out of the path of the shift lever, said pin restraining said shift lever from movement out of said reverse position when said solenoid output member is in said first position;
- an ignition control assembly having a rotatable control member, said ignition cable being operative in response to said solenoid output member to prevent rotation of said control member to a lock position when said solenoid output member is in said second position.
