If it is leaking at the shifter cable, then the manual lever shaft seal is defective and will need to be replaced.
Just an FYI..... It is not uncommon to see these units leak when they sit overnight or for a few days. The converter will drain back into the pan and the fluid level will then rise above the pan rail... then the gasket leaks. Not much you can do about it except "glue" the gasket to the pan and the case if it persists.

place one of the favorite places for the th400 to leak is at the detent connection. the reason is the plastic connector shrinks and the "0" ring can't seal. fix, jack up drivers side remove connector and use epoxy. jb will work. good luck ps clean all surfaces with brake clean similar stuff.
