All was going well with my lovely 240 (US) untill the past week.  Sure
I was leaking the quart of trans fluid every two weeks or so.  But, in
the last week the fluid has come gushing out of it-3 qts a day and hits
the exhaust creating horrific smoke .  It leaks like there is no end.
Surely, there is, like the end of the trans.

I see it dripping off a metal line from directly below. I have resigned
myself to the worse case scenario-that is- a used or rebuilt trans.

Okay, I guess I have a shop sheck for leakage source?

Also, how do I know if the trans has the notch for the crank sensor or
not unless it is removed form the car first?

Advance thanks
