vtecsti Posted February 27, 2021 Share Posted February 27, 2021 Hi there. I have a forester s turbo of 2000 vintage and I'm trying to establish what ratio the rear diff is... It's the auto box one... Gearbox code tz1a3zn2aa. Anyone know?! Thanks Quote Link to comment Share on other sites More sharing options...
savage bulldogs Posted February 28, 2021 Share Posted February 28, 2021 I have a transmission chart but it only has ty number gearbox info , unfortunately I can't help unless the gearbox number you wrote isn't correct . Did you take the number off the white sticker on the bellhousing near the starter motor ? Quote Link to comment Share on other sites More sharing options...
Mr B Posted February 28, 2021 Share Posted February 28, 2021 number seems correct. I assume it 4.44, you look for tags on rear diff ? 1 Quote Link to comment Share on other sites More sharing options...
vtecsti Posted February 28, 2021 Author Share Posted February 28, 2021 I haven't looked on the diff yet, it's not very accessible at the moment... All I seem to be able to find is that it could be a 4.111 or a 4.444, so not much help... I basically need a 4.444 diff for my Impreza, and was hoping the one off of the forester would do it. Any idea if they're LSD? I'm guessing probably not... Quote Link to comment Share on other sites More sharing options...
