You'll have to take it apart. All kinds of nooks and crannies with gunk in
them. Also springs and little BBs. I looked at that as a whole separate
evolution from the rest of the tranny, and even did it in a different
place. Lots of light and quiet. I used carb cleaner and picks on the thing;
some of that stuff was almost fused in those channels.
The tranny rebuild was a new experience for me and I was pretty paranoid
about screwing it up, but as it turned out it was pretty straightforward.
I'd had brake jobs that were worse in terms of difficulty and aggravation.
As I said: Lots and lots of pics. There's a set online somewhere, and I
still have mine if all else fails. Put 'em on a laptop in order and
reassemble going in reverse and it helps (or at least it helped me.) :)
