Gear Lockout: Description and Operation

System Description








At a vehicle speed of 12 mph (20 km/h) or more, a signal from the vehicle speed sensor (VSS) activates the reverse lockout solenoid, which pushes the select lock cam B into the locked position. As a result, the select lever cannot rotate to the reverse select position, making it impossible to engage reverse gear. At a vehicle speed of 9 mph (15 km/h) or less, the signal from the VSS is interrupted which turns off the reverse lockout solenoid. The select lock return spring gulls back the select lock cam B. enabling the select lever to move freely so reverse gear can be selected.
