I need some help diagnosing a problem with my 97 cherokee. It has a 4 liter 6 cylinder engine with 4 speed automatic. I ocasionaly get an error code of 45, which is for an open or shorted overdrive solenoid, and then of course overdrive does not kick in. I would like to know the location of this solenoid. I figure that it is located just inside of the tranny fluid pan, but am not sure. Because this problem comes and goes, I suspect faulty wiring, but I don't know what wires to check. If anybody can help, I would really apreciate it. Thanks.
