I am doing an engine swap on a 1990 cherokee and am having a hell of a time figuring out where a transmission line is supposed to go. Im not refering to the cooler lines, got those hooked up. The line I am refering to runs from tranny/torque converter? and is a rubber hose with a short metal L-shaped tube at the end with a bracket on it. It appears to parallel cooler lines and torque converter vacuum lines. Any help is appreciated.

 

I think it's a vent. Does it look like this? It's supposed to go to a nut on the bellhousing but I just zip-tied mine up high.

 

yep, that be the tranny vent

 

That's the one, thanks alot.
