the only way to find leaks is start 100% clean , drive short distances, and then look. (or the dye test methods)
it can only leak from a small number of sources. my 3sp page shows that.
9 ways?
pan (so it not the pan leaking, some even rust out and leak)
front seal (pump and TC) leaks to bottom front TCC inspection cover. and TC will be soaking wet if you look there. id 8, http://www.fixkick.com/tranny/slush/slid...ge_10.html
rear seal to 4wd adapter housing and down to vent, below,,, in there. see bottom vent here? http://www.fixkick.com/tranny/centerbox.JPG
shift rod, seals,
Kickdown cable connection (loves to leak we are told)
vacuum modulator, make sure nipple pulled it dont leak ATF. it has seal on the interface point seen here...http://www.fixkick.com/tranny/slush/slide3L30/html/image_14.html
dipstick tube seal.
vents (2 ways, direct and blocked tubes)
the electric TTC lockup wired jack has seal too. id 16, http://www.fixkick.com/tranny/slush/auto-base1.jpg
the top of the trans is a vent and if plugged up will make any trans leak even brand new. (the breather must breath or it builds pressure, (hot things expand) the hose there is shared to the transfer case breather, and goes up to the top of the rear side of engine an has this water blocking breather cap there, missing on many old cars now, so owners see empty hose there and think
its needs to be plugged up, and is wrong it's the 4wd high water mark breather hose same as both axles have.

and see leaks link?
best is clean it , drive it ,look, no better way exists....
yes the transfer case just unbolts from the adapter flange, that what makes TH180 a 3L30 is that adaption to 4wd. (box must me drained transfer first) but if the bottom adaptor vent is not leaking ATF why do that? there is a vent there, a tell tale vent .
and the hidden bolt top rear.? (not sure on 3sp but 5 has this nasty hidden bolt,keeping transfer case stuck there)
