Re: 92 Volvo 740 turbo is not going into overdrive:
I removed the O/D solenoid from the side of tranny. WIth iginition ON and O/D button IN to enable O/D, I have good power (test light) right at the solenoid. I have to touch the solenoid to the tranny pan of course, so that it will work. It is drawing quite a lot of amperage, I can tell. However when I cycle power I can feel little if anything as far as a vibration indicating that maybe it is activating. I hewar nothing. I thought it would probably have a very noticeable vibration and "click". The only way I will know for sure if it is good is to somehow see if fluid is alternately passing/not passing through the ports. They are very small, and I don't know how I could do this. I would need some VERY thin plastic tubing of just the right size to jam down into one of the ports. I guess there is a good chance the problem is this solnoid and not the tranny itself. But ...can the kickdown cable be so mis-adjusted as to prevent the O/D from kicking in?
Ideas?
