wtdash Posted June 5, 2017 Share Posted June 5, 2017 Hi and Welcome, Although covered on here, and online, the short answer is 'the 1996 should work'. I'm not saying you're 'wrong' about the input shaft, but this is the 1st time I've heard of that issue. What's the TZ code on the '96? Longer answer: Any transmission from '90-'98 will bolt up, but the Final Drive Ratio is the main difference: For Automatic = 4EAT - Legacy, Forester, Impreza: '90-'91 = 4.11 '92-'94 and all '91-'94 Turbos = 3.90 '95 are all 4.11 '96-'98 EJ22/2.2 = 4.11 '96-'98 EJ25/2.5 = 4.44 I suggest you read up some more as there are other things to watch out for.

Mike104 Posted June 10, 2017 Share Posted June 10, 2017 Big issue is reseating the torque converter. Often it seems like it is installed far enough and people try to use the bolts to pull the last quarter inch and end up breaking the pump resulting in an inoperable transmission. There are some good videos/posts on this on the internet (see wtdash post above) Quote Link to comment Share on other sites More sharing options...
idosubaru Posted June 10, 2017 Share Posted June 10, 2017 Should be the same transmission and swap all day long except final drive ratio. You can install any final drive ratio trans you want if you also swap the rear diff to match. Post a picture if the input shaft differences you're experiencing. Shouldnt matter but tell us the vehicles to be clear: 98 legacy what - 2.5 or 2.2? 1996 what - SVX Impreza Legacy AWD FWD 1.8 2.2 2.5.,...?

Subaru Scott Posted June 10, 2017 Share Posted June 10, 2017 Input shaft shouldn't be an issue anyway, since you need to be using the torque converter that came with the new trans. Do NOT try to use your old TC, because it will be full of metal/friction pieces from the failed trans. Sounds to me like, as Mike104 said, someone pulled the TC off, and hasn't got it seated all the way, leaving the trans looking like it is different.
