If I find the right transmission & gear ratio, is it best to find an impreza tranny? Aren't they made in Japan? Or are all the trannys made in Japan? Or maybe Legacy is from USA? Are they better? etc...

i have never read or heard a comment one way or the other.

i do not think it matters.

+1 doubt it significantly matters.

 

getting a bead on prior history/maintenance would be a better indicator i think. 

 

get one from an impreza with EJ18 - reasonable chance it's seen less taxing use from the small engine?

My impreza is an 1999 with screw on filter. I dont think an EJ18 will work, on my 99?

EJ18, EJ22, and EJ25 transmissions are interchangeable if not the same thing, if an Ej22 trans will work an EJ18 will work.  the issue for you is that yours is a Phase II transmission so you need to use 99 - 2002 transmissions and possibly 03-04 will work too.

i don't think you can use 98 and earlier as they are Phase I and electronically different from 99+.

 

if yours has the delayed engagement into drive issue that's specific to 99 only transmissions, there's an easy fix for that.

 

Oh - and a screw on filter - so that means we're talking about a 1999 automatic transmission, you never stated what trans you're talking about.
