05AWDGT Posted August 12, 2012 Share Posted August 12, 2012 I'm looking for a trans for my 05. I need to know what year will work, or if they are the same through 09? Also, is there any computer programming needed after swapping a 5mt? Link to comment Share on other sites More sharing options...
snowdrift86 Posted August 12, 2012 Share Posted August 12, 2012 I have an 05 trans for sale. The only problem is shipping Link to comment Share on other sites More sharing options...
Four_wheel_drifts Posted August 13, 2012 Share Posted August 13, 2012 I know they are the same through at least 2008. You can use one from the outback, too (BTDT), but the gearing is lower. There is a slight increase in cruising RPM, but the acceleration is better! Link to comment Share on other sites More sharing options...
05AWDGT Posted August 13, 2012 Author Share Posted August 13, 2012 So what year turbo outback 5mts would work? That might be cheaper... Does the Outback tranny hold up as well? Link to comment Share on other sites More sharing options...
BAC5.2 Posted August 13, 2012 Share Posted August 13, 2012 The transmissions are all about the same from 05-09. There were slight changes in synchro style, the later transmissions being a bit more robust, but gears are all about the same width. The only difference between the OB and the LGT transmission is the final drive. It's got a 4.44 vs. a 3.90. The shorter final drive (numerically higher) makes the OB trans inherently stronger, however. With any OB trans, you'll also need the OB rear diff.

I may be wrong but I thought the 05 was the only year that had the 4.4 ratio? :confused: Link to comment Share on other sites More sharing options...
snowdrift86 Posted August 14, 2012 Share Posted August 14, 2012 yeah and LGT had 4.11 not 3.9. the WRX has 3.9 buddy Link to comment Share on other sites More sharing options...
BAC5.2 Posted August 14, 2012 Share Posted August 14, 2012 I may be wrong but I thought the 05 was the only year that had the 4.4 ratio? :confused: As far as I am aware, all 05-09 OBXTs have a 4.44 with the LGT ratio gearset (the 3.166 set). The N/A OB has a 4.11 and shorter ratios (the 3.545 set). I assumed we were talking about An LGT trans, and so I was only talking about the XT trans. I should have clarified.

First, not all WRX's have a 3.9. The ones with 1.1:1 transfer gears have a 3.70 front diff. Second, only the 05-07 LGT has a 4.11. The 08-09, the one I looked up, has a 3.90. http://www.cars101.com/subaru/legacy/legacy2009.html#mechanical [URL="http://legacygt.com/forums/showthread.php/proper-flip-key-interesti-159894.html"]Flip Key Development Thread[/URL] "Genius may have its limitations, but stupidity is not thus handicapped." - E.

BAC5.2 Posted August 14, 2012 Share Posted August 14, 2012 To the OP, it looks like the only bolt-in for you, would be a 05-07 LGT transmission. Everything else would require a different rear diff, or a rebuild to swap your front diff into the new trans (or their shafts into your trans). The latter options are likely going to cost more than ordering a replacement for whatever broke and getting it fixed.

whitetiger Posted August 14, 2012 Share Posted August 14, 2012 only the 05-06 5mt had the 4.11 gears. 07+ went to 3.90 IIRC Link to comment Share on other sites More sharing options...
GTTuner Posted August 15, 2012 Share Posted August 15, 2012 only the 05-06 5mt had the 4.11 gears. 07+ went to 3.90 IIRC I was under the assumption of the same. Link to comment Share on other sites More sharing options...
BAC5.2 Posted August 15, 2012 Share Posted August 15, 2012 07's had the 4.11. 08+ had the 3.90 from what the OM's say. http://www.cars101.com/subaru/legacy/legacy2007.html#mechanical It could have been a poorly documented split year change, like Subaru did in 03.5 with the WRX.

1454 Posted August 15, 2012 Share Posted August 15, 2012 Here's the million dollar question, will a 06 wrx 5sp drop in a 05 lgt? I know the rear gear would have to be changed. But I can get wrx reman for cheap from a local guy. Link to comment Share on other sites More sharing options...

But I can get wrx reman for cheap from a local guy. It should. The starter mounts the same, and both use male axles. The output shaft is the same spline count, too. The WRX trans has a speed sensor you won't use, so don't worry about that. You would need a WRX rear diff, too.

mazdaslo Posted August 20, 2012 Share Posted August 20, 2012 Rallispec has put out an awesome chart Transmission ID Chart_Public.pdf is the file name that I found it under, but I have been searching around for it online again, and have not been able to find it. So, the 2005LGT has TY757VBAAB-a 5 speed transmission, with an open front diff, 1:1 center diff, 4.111:1 final drive and 27020AA050-a R160 w/ Viscous and the 2006 Impreza WRX has TY754VW7AA-a 5 speed transmission, with an open front diff, 1:1 center diff, 3.700:1 final drive and 27020AA050-a R160 w/Viscous if you want a copy of the chart, is is emailable, or i can send you a link to it on my google docs, shoot me a PM Link to comment Share on other sites More sharing options...
