I've seen posts that it will, but Car-part.com shows '90-91 separate from '92-94 when searching.

I did see where even a '95 should work.

I've got a line on a 48k mile 1994 for $350 that I'd like "just in case".

Any seals need replaced if it's been sitting?

Thanks!

I'd do the rear seals on the engine. The tranny should work just fine - no hitches.

As long as you get a matching geared rear differential of course.

The final drive ratio is probably different. I don't remember the exact years, but the first couple years of the legacy ran 4.11 gears, then they switched to 3.9s, then back to 4.11s in like 95 or so.

Here's what I've found out for 2.2 non-turbo 4EAT Gen 1 legacy:

The tranny wil fit, but the rear diffs are different:

'90-'91 = 4.11
'92-'94 = 3.90

If there is a 3.90 LSD (did they make this?) I'd change the rear otherwise I'll keep looking.

Thanks

There was a 3.90LSD available in 1991 on the Subaru Legacy SS. Not on the standard L and not after 1991.

Did that site have any other years listed? If so could you put up a link

My Bad.. I should've given credit where it's due.

There's no site that specifically stated this (that I found). But between USMB's/Legacy Central's (bbs.legacycentral.org) Legacy777, USMB's johnceggleston, Car-part.com (search on differential or carrier), ebay items, and a couple other posts here (that I can't find:mad: ) I pieced this together.
