Thanks gents for all the feedback and different perspectives. I pulled the
tranny yesterday and think I'll take a shot a taking it apart. Thanks also
for the links Robert, I hadn't come accross wittrans.com before.
Do I really need to dismantle the valve body or is there some other way to
get any gunk out? I am planning to replace the TC. Even with that,
hopefully I can get this done for less than $500 as opposed to the $2000
plus for a professionally rebuilt unit.
