It doesn't require any special tools - you need to set the brake band
tension in inch pounds, but that's about it. If you've rebuilt engines you
can do this, and I'm 98% sure that you are correct in that it's the forward
clutch.
Earlier today I described the process to someone as "painstaking". You have
to be particularly clean and well-organized. The fluid in the case and
internals will want to get all over everything. I did most of my work in a
large Rubbermaid bin lid lined with plastic. I took a picture every time I
did something - every stage, every time (and it saved my ass later).
You may want to go in for a reconditioned valve body if it appears to need
it (how many miles are on this tranny, do you know?). It isn't necessarily
likely, but it's an option. Cleaning the VB requires the most care and
attention (and lint free cloths) imo.
I would always replace the TC in doing this - the one you have is full of
friction lining material and other crap that you won't be able to get out;
it's my pet theory that that's the stuff that causes the cold shifting
problem these things get right before they die (choking up the vanes in the
TC until it gets warm(er) and they free up).
The last time I got parts for an overhaul I got them from
www.makcotransmissionparts.com and www.wittrans.com (I think because I
couldn't get everything at one place). The standard rebuild kit doesn't
quite have everything you need, so you need to make a comprehensive list.
Alternately, you could get a rebuilt from German Transaxle (which is of
course much more expensive than rolling your own).
Keep us posted!
