That "maze" is called the Valve Body, and
the BB is a check valve or a plug depending
on where it was.

I would say if the trans isn't slipping, it just
needs the valve body gone thru, a sticking
valve body causes the problem you are having.

One other point, you got some courage to go
digging into an auto tranny and you don't know
what the valve body is called 

Keep up the good attitude, you will learn lots,
I hope your next project works out like you want

Thanks - I still thought this was a lot of fun.  As long as I can keep one car driveable at all times, I don't mind diving in way over my head on the other - and I learned a lot on this.

Now I've been through the drill a few times, I won't hesitate to drop the pan and change
the fluid and filter and gaskets etc... in the future.   Since I'm so far into this tranny thing now, I'm considering trying to drop the whole tranny myself - I think I could get that old kickdown cable out if I could just get access to the top of the tranny housing.  But since I don't even know names to stuff, and the Haynes manual sucks, I don't know if I've got the courage for that unless I can find a FSM somewhere.

I forget how that cable hooks up but I dont remember having any problems. I rebuilt mine myself, cost like $100 for the bands and clutches, it wasnt any harder than rebuilding an engine. Mine works great now, wouldnt hesitate to do it again

I've always wanted to learn how to rebuild a transmission - so I'm going to try it myself.
Finally found real Service Manuals at books4cars.com, they had one listed for the Suzuki and three for the Tracker - so I ordered the Tracker books (getting parts from a local chevy dealer anyway). 

Hopefully these will tell me what I need to know:
 91 Tracker Service Manual by Geo (91_Trak_Svc)  $39.95
 89-93 Tracker Parts & Illustration Catalog by Geo  (91_Track_Part) $59.95
 91 Tracker Electrical Diagnosis Service Supplement by Geo (91_Track_SvcSup)  $12.95

Anyone know if these will cover the transmission too or if there is another book for that?
Thanks,
-Scott

yes, they cover a trans rebuild well.
