The cable is pushed in for the overdrive to engage and pulled out to disengage. The kick down switch is to disengage the OD temporarily similar to a passing gear in a vehicle with an auto trans. The overdrive will "freewheel" under 30mph when you let your foot off the accelerator. In normal driving when you are up to speed you let off the gas and it shifts into OD similar to the shift in an auto trans. If it freewheels above 30mph the OD is not working properly.There is lots of information on these transmissions on this forum.
