whatcha doing shawn? rebuilding, replacing?
 
Wasting my time as it turns out.

Initially i wanted to replace the seal between tyranny and t~case. The t~case has been pumping into the tyranny, and i wanted to get rid of the jerry-rigged return line running down from the tyranny fill plug to the t-case fill plug. When i got in there i found out that the seal indeed needed to be replaced, but the real problem is that the tyranny output shaft was worn by the t-case input gear, making for a spline pump that would cost about 700$ to fix (new output shaft). And even then, it would still be softer than the t-case gear and wear all over again. That is a guaranteed failure point of the 4 speed, and something Toyota should be ashamed of. so the moral of this rant is that the "jerry rigged" return tube is the correct fix for when your t-case pumps all of its gear oil into the tyranny.

So while i had the tyranny out I put all new gaskets and seals on it and the t-case, replaced all clutch components (the bread trick is THE way to remove even the nastiest pilot bearing), dropped oil pan and put in new pan gasket and rear main seal.

sounds like fun. didnt know you had a 4 spd.
 
Wow I had a leak and thought it was a rear main seal after dropping the tranny turned out to be both freeze plugs, rear main seal still looked new even had the grease still on it. When it dripped the oil came around and dropped at bottom similar to rear main seal.
 
Did you check to see whether the oil galley plug was leaking? That one can turn into a gusher. My RMS was OK too, but i figured i'd go ahead and replace it--dropping the tyranny is not something i enjoy doing.

On the bright side, the clutch feels super nice now...
