I been fooling with this 700R4 for a long time now. I have replaced the front seal, Tcc solenoid, pump bushing, pump gasket, O ring and dipstick gromet. It is leaking from directly behind the TC...it seems to run down the TC and spackle onto the bellhousing untill it begins to drip from the two bottem corners on the bellhousing. I have a spare TC it has the number "6" stamped on it my current TC has a "7" stamped on it, whats the difference? What else can it be my flywheel doesnt seem to whoble...If i buy a complete tranny with TC and transfer case should that solve my problem or can it be a problem with my flywheel...Thanks everyone...Sorry for such a long post.
