1992 Volvo 940 4 cyl Four Wheel Drive Automatic
I have a '92 Volvo 940Gl where the 4th gear will not disengage when I push the pushbutton switch on my shifter and the disengage arrow light on my dashboard remains on. It feels like it is stuck on either 3rd or 4th gear. Could the problem be either the service overdrive switch on my shifter or my overdrive relay? Where is the overdrive relay located if I have to replace? Also the shifter pushbutton swith, can I remove it easily or I need a train mechanic to do it? I am a do it yourself mechanic and I'll try my best to repair my own car. Please help me.
