M/T Reverse Lockout System Description (K24A3 M/T)

M/T Reverse Lockout System Description

At a vehicle speed of 20 km/h (12 mph) 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 15 km/h (9 mph) or less, the signal from the VSS is interrupted which turns off the reverse lockout solenoid. The select lock return spring pulls the select lock cam B back, enabling the select lever to move freely so that reverse gear can be selected.
