Subaru manual transmissions are pretty well built and have minimal problems. When failure occurs there are usually just a couple of things that fail. The most common problem is bearing failure causing the transmission to be noisy and if it's excessive your trans will sound as if someone has put rocks in it. The center diff can be replaced without removing the transmission from the car. The tailhousing unbolts from the back of the trans and the center diff slides right out. Hardest part is getting the double roll pin out of the shift yoke. Your transmission is a Phase 2, so you'd need to get a replacement from a 2000 or newer trans.
