This is my attempt to convert from Subaru AWD to 2WD tranny using their own internals.

So…! I pulled the engine out and I’m going for a Subaru tranny.




I pulled out the transmission cover and removed the differential.




I put the whole differential in a flat surface and make 2 tag welds to fix in position the whole differential.





I did a test fit on the transmission, to be sure that the gears did not moved during the tag welding. Did the necessary measurements to cut the differential. Then proceeded to cut the differential (had to pullout the bearing first).

Another test fit on the transmission.


Decide to cut an outer ring so I can Tig weld it.




Mig weld to maintain position and prevent warping during Tig welding.



Test fit again in the transmission.


Proceed to TIG weld



Did Tig weld in the inner side in 3 sections. Really the outer weld look so strong and have so much penetration that I was thinking that the inner welding was not necessary. And also had to grind a little in the inside since the Tig weld got to the splines in some sections.




Test fit on the transmission.



Just a washer away.




BTW I'm using a WRX 2006 transmission.
Hope this help.
