Gear Lockout Solenoid: Description and Operation


The 2/3 lockout solenoid prevents driver from shifting into second or third gear during certain operating conditions. The 2/3 lockout solenoid is controlled by the PCM.

The PCM locks out second and third gears, when:

^ Engine coolant excedes 98° F (37° C)
^ Vehicle speed is 12 to 18 mph.
^ Engine speed over 608 rpm
^ The PCM verified above conditions
^ Throttle position is less than 23 percent

The PCM resets the solenoid when vehicle speed drops below 2 mph.
