Will do... In the mean time, I don't have jack stands so I peered under the car with a flash light and saw a hose that sags down from around right under where the driver seat is.

It is badly misshaped. Looks like its caked in gunk, but feels just like soggy, sticky, disintegrating rubber.

Is this the line I should check for oil?

EDIT: Sorry, I'm a very green DIY'er, if there is ATF in the vacuum line, does that mean the ATF is going into the engine? Possibly a cylinder? What are the implications of this?

Is it burned up by the engine?
