Default 04 WRX to 07' trans swap

I was wondering if anyone can help me out here, I heard that this is possible and would like to do it to ensure that my car will be able to handle the new 2.5 shortblock I'm swapping into it.

Other than the 04 WRX and the 07 have different ratios, and you have to address that issue, they do bolt up.

keep in mind that the 07 trans has a 3.7 final drive ratio when you pick out the rear diff you are going to use. You will also need new axels if your 04 transmission has axel stubs. the clutch on your 04 is a pull type, and the 07 is a push type, so you will need a new clutch, new slave cylinder, and probably a new flywheel. If I think of anything else, I'll post it for you
