bt714 Posted July 14, 2006 Share Posted July 14, 2006 Hi, new to this site, was wonderin if anyone could help me out. We have a 1993 Impreza, with 163,085 Miles. other than the usual oil leaks and such, it runs pretty good yet. only major problem right now, is that in the winter time, when the roads are bad, it doesnt want to kick in the rear wheels the way it should. last winter, it seemed that I had to almost work the throttle to try and get it to engage. and when it would, it did so with one heck of a clunk, almost as if the only way it would kick in, is when the fronts were slipping alot. I have owned four wagons before, (man do I miss them) they were all manual select 4WD, never any problems with them, so never had to figure them out, but this one, it has me baffled since I am not at all familiar with the AWD workings. I appreciate any info, and thank you in advance. Hope I can be of some help with some questions to come. Link to comment Share on other sites More sharing options...

ericem Posted July 14, 2006 Share Posted July 14, 2006 Seems my my 93 leg. I suggest u do a tranny flush, because the clutch for the awd gets guky, and doesnt engage. But with my 93 leg at the time i didnt know so, i burnt out my drive solenoid that kicks in awd. Link to comment Share on other sites More sharing options...
bt714 Posted July 14, 2006 Author Share Posted July 14, 2006 i burnt out my drive solenoid that kicks in awd. I was wondering if the tranny fluid could have anything to do with it,.. will do the serch suggested, If the Drive Solenoid burns out, will it kick in the awd at all??? and WOW, talk about quick service, hell, McDonalds aint got nuttin on this place!!!!

ericem Posted July 14, 2006 Share Posted July 14, 2006 BURN!! anyway what happens is the clutchs get gunky thats all. ANd a flush usually fixes the issue. Link to comment Share on other sites More sharing options...

If it gets really bad, they weld themselves together, mandating replacement of the clutch plates or clutchpack unit. Link to comment Share on other sites More sharing options...
johnceggleston Posted July 14, 2006 Share Posted July 14, 2006 as i have read here over the past 6 months, there are 2 things in the trans that can cause tourque bind. 1. duty c solenoid - electric failure or gummed up electric failure you had to pull and replace the sol. ( don't let them trick you into thinking that the clutchplates are bad too. matbe, maybe not.) trannys around 95 had the tendancy to gum up the duty c valve seat. this was corrected in 96/97. changing the trans fluid could usually help. 2. clutch plates - gummed up? or welded together (not sure) running long term with torque bind caused by gummed plates or duty c, i think, could lead to welded plates. fluid change could help gumming, but only replacement parts can help welded plates. $850-1000. i spent $275 labor putting in a used clutch pack, duty c included. ( i knew the trans, no TB) if you go this way i suggest a new duty c in the process. you would hate to have a duty c failure 6 months after replacing the clutch pack. ($275 labor again) good luck. Not true. If it gets really bad, they weld themselves together, mandating replacement of the clutch plates or clutchpack unit. Link to comment Share on other sites More sharing options...
pamike Posted July 14, 2006 Share Posted July 14, 2006 i had a problem like this and everyone seemed to think my clutches were bad. i lifted the wheels off the ground and only the front would spin until i gave it some gas then it would clunk really loud and the rear would spin a little and stop again. i unpluged the wire that goes to the solonoid and the rear spun fine. so i spliced a switch into the duty-c wire and when i need awd i flip the switch. http://www.ultimatesubaru.org/forum/showthread.php?t=60016&highlight=pamike Link to comment Share on other sites More sharing options...
Manarius Posted July 14, 2006 Share Posted July 14, 2006 *sigh* Torque bind is not a sticky solenoid C or worn out clutches. Torque Bind is shutter during low speed and/or sharp turns. Clunking AWD is almost always solenoid C being worn out. Link to comment Share on other sites More sharing options...
Setright Posted July 15, 2006 Share Posted July 15, 2006 This is funny, in the peculiar sense, since there has been no question or confirmation of the type of driveline. My manual tranny ain't got no solenoides Link to comment Share on other sites More sharing options...
nipper Posted July 15, 2006 Share Posted July 15, 2006 sigh. Torque bind in its purest defanition is when there is no speed differnce between the front and rea axles on turns. The front axle turns at a differnt speed then the rear axle on turns, and there has to be some way to compenstate this. on automtics its a clutch pack. The clutch pack is designed to allow for slippage on turns, but wont tolerate alot of slippage. A failed duty c solenoid or welded clutches can cause torque bind. No response to the rear wheels is the reverse problem. This is just like a slipping automatic tranny. The AWD unit is working fine, except your clutches are glazed/worn/wiped. There is no more clutch material on the discs, so like any clutch, its slipping. Installing a switch forces the awd curcuit to go to max pressure (putting the car in low will do the same thing). This will work, but only for so long. In the meeantime you have lost the sfatey of AWD traction in all conditions. The AWD works not just in the snow, but it works extreemly well on dry surfaces as well as rain. There is a reason you cant get a sooby to spin tires when the front wheel is cut hard. nipper Link to comment Share on other sites More sharing options...
Manarius Posted July 15, 2006 Share Posted July 15, 2006 *sigh* Please read before you mis-interpret torquebind. http://legacycentral.org/library/torquebind.htm Sloppy clutch packs and solenoid C being busted is cause for AWD not to engage, not for the infamous torquebind as described by most early Legacy owners.

Otherwise your correct now lets all sigh together, then go over to the gas mileage thread and sigh there one two three SIGH nipper Link to comment Share on other sites More sharing options...
bt714 Posted July 15, 2006 Author Share Posted July 15, 2006 unfortunatly, I think I am getting more confused as to what the problem may be now. yes, it is an auto trans. will the fluid change still help the cause? I do not have a clue what the "duty c" solenoid is, or where it may be. Link to comment Share on other sites More sharing options...
