Default 4eat fitment

I have a 4eat transmission that I removed from my 07 WRX when the 6speed got installed. I was wondering if this transmission will fit in a 06 Impreza Wagon. My brothers 06 front diff is on the fritz and I was hoping to swap this in for him. They are both 2.5L

Any and all info is greatly appreciated.

Thanks, Curtis

The 2002 - 2007 frames/cars are pretty much the same and many parts are interchangeable.

Does your brother already have a 4EAT?

What you have to be sure of is the gearing in the transmission and rear diff. They have to match up or you will damage a transmission. It's not just a direct plug and play.

If you look here https://en.wikipedia.org/wiki/List_o..._transmissions it seems to be saying that the same 4EAT was used up to 2008, so you may be all set.

You should do some additional research.

Do the 2.0 and 2.5 use the same 4eat?

Yes.. But the axles changed from female to male some time around 2004. You an still swap the transmission, everything will work. But you might need to change axles depending on the year..

4EAT are not as interchangeable as the 5MTís are. the electronics are different.

even if everything fits mechanically, the signals needed are not present to allow the ECU and TCU to communicate properly.
