Frank B Posted July 15, 2006 Share Posted July 15, 2006 The detent or kickdown refers to the mechanism that downshifts the transmission into passing gear or a lower gear to accelerate in an automatic car. If yours is not an auto, it's confused. I thought the tranny was controlled buy a vacuum modulator that uses a vacuum signal from the engine to control when it shifts. Look on the sides of the tranny for a round metal unit, maybe gold in color with a rubber vacuum line going up to the engine. There MAY be an electric solonoid that the vacuum line connects to. The computor or another sensor controls when the solonoid opens alowing the modulator to get a signal. The connection may be dirty or the solonoids bad. Also try resting/clearing the computor. You may be able to disconnect and bypass the solonoid all together, but that may trip a fault code too. This may help. http://www.ultimatesubaru.org/USRM2/mick-usrm/electrical/ecucodes.html Quote Link to comment Share on other sites More sharing options...
sporta Posted July 15, 2006 Author Share Posted July 15, 2006 Oops sorry. The car has the EA82 SPFI motor in it and the 3sp auto tranny. Where is this darn thing located ? Thanks again Quote Link to comment Share on other sites More sharing options...
hooziewhatsit Posted July 15, 2006 Share Posted July 15, 2006 the kickdown solenoid will be on the passenger side of the transmission, with two fairly heavy wires going to it. Under the steering column, there should also be a switch that is pressed when you press the gas to the floor. To test the kickdown solenoid, you can unplug its wire harness from the transmission, then put 12v across the two wires. Polarity doesn't matter. You should hear a 'click' come from the solenoid. If no click, then it's bad and will need to be replaced, and/or worked around for the time being. If it is bad, you can try hooking up a ~60ish ohm, 10W resistor into the computer side of the plug. That should make the computer think the solenoid works, and turn the CEL off until you have time to replace the solenoid. Quote Link to comment Share on other sites More sharing options...
