Yeah, I used the same guide the first time. Now it's a snap. It is a good resource. The first time though, you should do it with a friend because it takes a lot of practice to be able to put it all back together with only two hands; plus you can catch each others mistakes. The first time I took apart my gearbox, I had the anti-reversal latch going the wrong direction so the gears spun opposite. Fortunately, my friend caught what would have been a catastophic issue for the wellbeing of my gearbox internals.
