Just trying to figure out what manual transmissions interchange with my Legacy. Most Subies in my neck of the woods are autocrapics so wondering what years Impezas, Foresters, Leagacies manual transmissions interchange without modification.

Depends on trim level because you need to match the final drive (differential) ratio.

The ratio differs between trim levels. You could have either a 3.9 in a base or L model, or 4.11 in an Outback or GT model.

On the upper drivers side of the transmission bellhousing is a sticker with a ten digit code on it. Something like TY752V.... The code can be looked up on the transmission chart (search google to find it) and that should tell you the FDR of the trans you have.

 

Basic differences between years were not numerous. In 99 they changed the number of holes in the bellhousing but the trans will still bolt up the same. There are some issues with the starter mounting bolts in the post 99 transmissions though.

I'd try to stick with something between 95 and 98, but you could use one from as far back as 90.
