Help!!
 

I'm splitting my auto trans to replace the band brake. Can anyone provide me with an exploded view, or some diagrams please.

Okay, I got it apart and changed the band, but noticed that the gear on the front of the trans (for the front diff) has about a half of one of the teeth missing! This is major.. I checked subaruparts.com and they do not have it. it's the one on the shaft marked #1 in the image. Can anyone tell me where I can get one of these?! I'm pretty sure that my trans has stock gearing.

That's the pinion shaft, you'll need both a ring AND a pinion, as the gears are a matched set. Good time for a 3.90/4.11/4.44 gear swap :)

so it's just the ring and pinion that make it a 4.11/4.44?! but where can I get a 4.11/4.44 gear set? what year, and what car did they come in?
