04 WRX swap/possible rebuild.
As you know I bought a 04 wrx with transmission issues. The rundown.. Car shifts smoothly, and runs fine in all gears. Extremely loud squeal of metal on metal noise coming from tranny or maybe center diff. Trans oil was low added some and made a small difference but damage is already done. So I'm doing work at home. Start with diff or pull tranny out? Rebuild it and spend $$ on rebuilding the 5speed or should I look into doing a sti 6 speed swap?
