angerthis Posted October 31, 2014 Share Posted October 31, 2014 I have A 91 legacy 2.2 AWD With an automatic transmission You know the one that has the button for the manual shift And everything will fit fine but will it operate correctly For the traction control I was wondering if The transmission from a 94 legacy 2.2 AWD Would interchange Because it does not have the button for the traction control manual shift l Understand you can swap them out And everything will fit correctly but will it function correctly Has anybody dealt with these transmissions too much thanks for reading this if you need more detail just ask I can give it to you thanks Link to comment Share on other sites More sharing options...
angerthis Posted October 31, 2014 Author Share Posted October 31, 2014 Oh yeah The other car is automatic as well Link to comment Share on other sites More sharing options...
porcupine73 Posted October 31, 2014 Share Posted October 31, 2014 For one you'd have to verify they have the same final drive ratios. Some old info I was looking at shows '91 Legacy AT had a 4.11 ratio while '94 Legacy AT had a 3.9 ratio. If that's the case you'd have to swap the rear differentials as well. Not sure if there's any differences such as # of flywheel bolts but others will likely know all those details. Are you sure the '94 doesn't have the manual button? I have a '94 2.2L AT Legacy and it has the manual button. Also you might need to swap the TCU's if you want to get the right shift points. Link to comment Share on other sites More sharing options...

Ya i know the 94 has no manual button on the shifter So what do you think my out come would be? Link to comment Share on other sites More sharing options...
idosubaru Posted November 2, 2014 Share Posted November 2, 2014 91's have a common problem with an easy fix of adding on a special filter or hose or something. are you sure you don't have that common 91 automatic legacy only issue? Link to comment Share on other sites More sharing options...
idosubaru Posted November 2, 2014 Share Posted November 2, 2014 you could compare 91 and 94 TCU pinouts via FSM's to see how close they are. Link to comment Share on other sites More sharing options...
porcupine73 Posted November 2, 2014 Share Posted November 2, 2014 Oh right on '91 was one of the years where they had that add on ATF filter that looks sort of like the fuel filter. I think they (and other makes) had trouble with AT clutch and metal shavings clogging up the cooler in the radiator and blocking the ATF flow. This was the 'kit': Link to comment Share on other sites More sharing options...
idosubaru Posted November 2, 2014 Share Posted November 2, 2014 that's it - that needs installed and the radiator cleaned out/bypasses if you're having 1991 AT issues. Link to comment Share on other sites More sharing options...
angerthis Posted November 4, 2014 Author Share Posted November 4, 2014 My 91 has a lot of miles on it like 3060K Just put a brand new engine in it Still the regional transmission it shifts perfectly fine But it's got that common torque bind problem with the four wheel drive its my girlfriends car and she can't stand it doing that I tell her just to deal with it its not that bad But can be annoying when you're turning sharp that extra filter that's not going to cause that torque bind correct? On the dash when you start the car it does have that blinking light that says power I was told it could be the duty C solenoid but I was also told it could be the clutch discs seized together thanks for all your help Link to comment Share on other sites More sharing options...
mikaleda Posted November 4, 2014 Share Posted November 4, 2014 Yes the filter could be the problem, I just went through this on a 91 legacy wagon. It was exhibiting sihns of tourque bind and it ended up being the filter was clogged changed it out with my own system and now it works fine. I also put in an Extra oil cooler as well. A word to the wise use Subaru genuine filters only the after market filters suck Link to comment Share on other sites More sharing options...

A word to the wise use Subaru genuine filters only the after market filters suck What kind of system did you come up with for your car? does the transmission actually need that second filter Or can i just bypass it And put in an external oil cooler for the transmission And eliminate the one that goes to the radiator Link to comment Share on other sites More sharing options...
mikaleda Posted November 5, 2014 Share Posted November 5, 2014 (edited) I used a home heating oil filter plumbed inline before the coole. The casing with filter was $27, not much more than the OEM filter and has more capacity but the best part is the refills are only $8. I had to run the cooler lines to the other side of the car so I had room for the filter but all in all it ended up making the filter a lot easier to service.I'm planning on taking some pictures of this system and posting them on the board so you can see where I put everything. Yes you can bypass the filter to see if that is your problem, but I wouldn't do that for long because it will clog the cooler even an after market cooler.

What kind of home heating filter did you use? is it for like something that was in the house for a burning oil for heat Link to comment Share on other sites More sharing options...
mikaleda Posted November 5, 2014 Share Posted November 5, 2014 (edited) Yes exactly its for a home heating system. I picked one up at the local hardware store brand new for $27. If anything it will filter better than the OEM filter since its designed to filter out anything big enough to clog the jets in an oil burning heater which is way smaller than something that's going to clog an oil cooler. And its slightly bigger filter than the OEM one Edited November 5, 2014 by mikaleda Link to comment Share on other sites More sharing options...
johnceggleston Posted November 6, 2014 Share Posted November 6, 2014 use this link to see if the final drive ratios match. i do not think 91 and 94 are the same. 91 = 4.11 94 = 3.9 but double check. Final Drive Ratio 90 - 94 Link to comment Share on other sites More sharing options...

mikaleda Posted November 7, 2014 Share Posted November 7, 2014 (edited) I have the pics I just have to get to a WiFi spot so I can upload the pics to photbucket and post them on here. One thing you can do just to test it out is just hook the in and the out right at the trans (bypass everything) and see if it helps, that will tell you imediatly if its going to work Or not Edited November 7, 2014 by mikaleda Link to comment Share on other sites More sharing options...
