Question
in a previous answer you said something about a vacuum load sensor for the Overdrive. I was curious if you new how to locate the sensor

Answer
Dean,

There is a vacuum sensor on the intake that lets the converter know when to lock up.  The fourth gear (overdrive) runs off the throttle position cable.  If the car is not shifting into fourth gear check to make sure the cable is working properly by having someone press the throttle, with the engine off, to the floor and noting the tension on the throttle valve cable.
