Vader Posted October 10, 2019 Share Posted October 10, 2019 This may has been asked before but new to the legacy world. I have a nice 2.5I auto wagon. That's what I wanted / searched for. All my cars are stick, I want to buy a 5speed manual GT donor car which I have leads on. Did the 2.5I Manual 05-07 Legacy's share the same transmission and diff as the 5 speed manual 05-07 Legacy GT's? Thanks in advance. Link to comment Share on other sites More sharing options...
Nonamedude Posted October 10, 2019 Share Posted October 10, 2019 I don't believe they do. I can say that the fsm for 08 shows a different gearing but the same final drive. I thought the final drive on the lgt was 4.111 but my fsm says 3.9. I'm not the most knowledgeable on this but a different fifth gear with the same transfer reduction and same final drive means either different rear diff or different tires or maybe both?

Nonamedude Posted October 10, 2019 Share Posted October 10, 2019 So definitely a different transmission. I'd guess the lgt has the type ra gears and the 2.5i does not. I believe the lgt uses the same transmission and rear diff as a wrx and the sti and spec b have the same rear diff. Spec b has a slightly different 6spd trans though I believe.

Zac88 Posted October 10, 2019 Share Posted October 10, 2019 05 gt is 4.11 gears, I believe 06 and up is 3.90 Link to comment Share on other sites More sharing options...
Vader Posted October 10, 2019 Author Share Posted October 10, 2019 Thanks guys, the final drive isn't a big deal as that can be swapped out as well. Was having a hard time searching for 1st through 5th ratios and trans model for comparison between the 2.5I's versus the GT manuals. If 05 GT is a different FDR then the 06+ that's good to know as well. I will keep digging Link to comment Share on other sites More sharing options...
Nonamedude Posted October 10, 2019 Share Posted October 10, 2019 Check out the vacation pix. There should be some for each year. That will give you the exact gearing for each model. That's where I pulled my info from Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
