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.
