Hey all, I have a 02 wrx and broke the stock 5speed so there's a local jdm shop that I got a tranny and rear end from. I got told the rear matches the tranny but the test drive doesn't seem so. It was supposed to be swapped to a 4.44 final drive and the tranny number is saying its a 4.44....so my question is other than pulling the rear diff cover can it be identified? There is a stamped number on the bottom, kn31. Any help would be really great!
