Pretty much any auto from 95 to 99 (98 for Forster) should work fine and possibly newer stuff as well though there might be wiring differences..... you may have to change to the matching rear diff for whatever you get or swap your original front diff over to the replacement if it's good.

As long as you have matching final drive with the rear differential then you should be fine.

more specifically, any auto trans from a 2.5L car, (outback, GT LSi, whatever) 96 - 98 will bolt in and plug in and work just fine. the final drive will match and it will run great. the only issue will be the speedo, if the stock tires of the donor car are different form the stock tires of your car then the speedo will be a little off. but the trans will run great.

you can also use any 95 - 98 auto trans from a 2.2L car as long as you get the matching rear diff.

some, a very few, 99 outbacks will also work and match the final drive, but at some point in 99 the outback went to the phase 2 trans and the wiring harness changed as well as the trans code number. making it work is a challenge, if not impossible.

when comparing trans code numbers, any trans that starts with TZ102Z2.... (the last 3 characters do not matter, they refer to the model the trans was in) will work, the second 2 after the second Z is the final drive identifier. 2.2L cars have a letter in that position.
