I have a 2000 2.5 5speed manual Outback. What years and models are interchangeable with my 2000 OB??

i doubt you'll get a solid answer on this. exact transmission interchangeability questions are usually not answered very precisely. find out what final drive ratio you have. (probably 4.11 or 4.44...but maybe 3.9). any transmission from a 2.5 liter subaru will bolt up just fine, make sure the final drive is the same. (although even if it's different you could swap the rear differential as well).

 

i can't recall when major changes were to the 2.5. try nasioc as well they would likely know the major changes the 2.5 went through (if any). as far as i know any transmission from a 1996 - 2001 2.5 liter will bolt up just fine...just make sure the final drive ratio is the same as yours or you swap rear differentials (very easy..it's like 3 bolts) as well.

thanks now I can do some more searching and expand my search

What are you looking for? Just a replacement of what you have, or some different options?

I just want a replacement of the transmission. I will use whatever will work.

Any EJ series transmission will bolt up if you get a matching rear differential.
