2-Turbos Posted May 13, 2011 Share Posted May 13, 2011 Ok, first off, yes I did a search, and it didn't return anything helpful. So here's the back story -- installed a Jazzy Engineering iPod integration system this morning. Everything went perfectly smooth, all the parts came out and went back beautifully. The problem -- took the car out for a ride, and discovered the transmission is having issues. It will not upshift in auto mode, you have to use the thumb buttons or put it in manual and bump it. When you try to downshift, the buttons/shifter do nothing, it has to be put in auto mode so it can downshift on its own as the car slows. WTF is going on?!? Did I somehow dislodge a connector on the side of the shifter that would cause this? I checked all the fuses that seem to relate to the transmission in some form, and all were good. Please help!

snow05gtRI Posted May 13, 2011 Share Posted May 13, 2011 there is a plug in there that controls the shifter, yes. but you're saying the shifter works in manual mode? Link to comment Share on other sites More sharing options...
2-Turbos Posted May 13, 2011 Author Share Posted May 13, 2011 The shifter works UP in manual mode only. Trans shifts down in auto mode only. Whichever mode I use, it'll do half. Link to comment Share on other sites More sharing options...
snow05gtRI Posted May 13, 2011 Share Posted May 13, 2011 probably dislodged the plug or something. there's a white plug near the shifter when you lift up the dash area. Link to comment Share on other sites More sharing options...
2-Turbos Posted May 13, 2011 Author Share Posted May 13, 2011 Sweet. I'm kinda hoping its just something that stupid. At least I've got a place to start later. Thanks! Link to comment Share on other sites More sharing options...
fishbone Posted May 17, 2011 Share Posted May 17, 2011 Let us know what it was, I am about to do the aux mod this summer. Link to comment Share on other sites More sharing options...
2-Turbos Posted May 18, 2011 Author Share Posted May 18, 2011 Heh heh heh. If I knew...... Took the car to the stealer (are we allowed to refer to dealers as stealers on here? I apologize if not.) on Saturday morning. Their best tech with 25 years in the Subaru business took one look and went He had never seen this issue. So he zapped this memory, that memory, whatever. Nothing happened. So I left the car over the weekend and on Monday they called SoA to ask what to do. SoA said try bleeding some hydraulic line or some sh!t. So the tech started that, but went to a dentist appointment on Monday afternoon and went home after, saying it'd be done by Tuesday around lunchtime. I call at 130 yesterday, and they're like, "we haven't touched it yet. Call around 430." At 430 they say "we're still not sure. It should be done sometime on Wednesday." So I'm climbing the walls right now.....:soap_box: I honestly don't think the aux mod caused this, rather it's just a freakish fluke. I'll update this when and if I ever get my car back.

snow05gtRI Posted May 18, 2011 Share Posted May 18, 2011 did you ever check that plug? Link to comment Share on other sites More sharing options...
2-Turbos Posted May 19, 2011 Author Share Posted May 19, 2011 Yeah, the plug wasn't the problem. Turns out something in the TCM fried itself. Only took 2 techs and 5 days to find it. I'm not sure if it was a fluke, or if I somehow caused this. Either way, by the time all is said and done, I'll be $800 poorer and without my car for the better part of 2 weeks, at minimum. Lesson learned here - when you're screwing around with electronics, unhook the damn battery......I know better, too. Not sure if it would have made a difference, but at least I could have eliminated myself as a possible cause. *sighs* Link to comment Share on other sites More sharing options...
fishbone Posted May 19, 2011 Share Posted May 19, 2011 Ouch! Hey, I'm with you. I've done stuff on the car before with the battery connected because I figured it was safe. No more ... Link to comment Share on other sites More sharing options...
ClimberDHexMods Posted May 27, 2011 Share Posted May 27, 2011 Fried control module was my guess as well. Sounded software related, since you could actually drive it fine, it just was without a brain.

2-Turbos Posted May 28, 2011 Author Share Posted May 28, 2011 Finally got the car back on Wednesday. Turned out not to be the TCM. It was the actual shifter assembly itself. There was a short somewhere. It was entirely electrical, not electronic in the least. Who knows, I'm just glad to have it back. Link to comment Share on other sites More sharing options...
ClimberDHexMods Posted May 28, 2011 Share Posted May 28, 2011 Nice! And interesting. There are test procedures for every single one of those wires. Glad they found it. Wonder what had shorted.
