FMX question
 

So I'm making the final preparations to fire up my car for the first time since the rebuild, and I'm a little hung up on something:
On the transmission (FMX auto) a hard line comes out near the front of the case and then turns down near the tail shaft on the side opposite from the vac modulator. It looks like there should be some kind of soft line hooked to it, but I don't know where to connect the other end. I know it's not a cooler line, because I've already hooked those up.

Thanks for any advice you can give.

Is it the vacuum line for the vac modulator?? I know that sound kind of obvious, but some things just got to be asked!!

No, that's not it....wish it was that obvious. Everything I can think of already has a line on it. At first i thought maybe it was a vent tube or evap or something, but that doesn't seem right.

It's the overflow. In the event of overfilling your tranny it will puke through that, and onto the exhaust creating big clouds of white smoke. And very slippery roads! I found that out the hard way can ya tell.

Ah, thanks. I was baffled by that.
