I can't see any useful purpose for it so i would just connect the two lines with a coupler fitting.

 

Was thinking the same thing, on top I can't remember if it has wires or another line wrapped in the heat shield , either way I will need a 3 way type connector or a replacement part if it's wires. I will post a better picture of the top half when I get back home.
And thanks for your response 🙂

Moved.

 

I'd take it to a good transmission shop. Surely they can tell you. It looks like a pressure switch to me.
No where could I find a diagram.

 

On many models of these years, the tranny's had a line temperature sensor (might be what that is) installed externally. Many of these older metal fittings corrode and begin to leak over time. Take it to a good transmission shop, or find a hose/line rebuilder near you. Most of these parts are impossible to find new, and even if one existed, I'm convinced the knowledge of the local dealership parts manager is usually lacking to find it. Building from scratch is usually the best guarantee you'll get the job done.

 

My guess is that the part itself is fine. The fittings are likely fine as well or can be easily replaced. What actually failed because of the rust is the tubing. So, you can repair them just like you repair blown/rusted brake lines.
New prefabricated lines, flairing tool, fittings, unions, tubing, etc. Usual stuff. Any shop should be able to handle that repair. If you disconnect the lines, they will likely fall apart.

Vehicle sat for 2 years shocks, brake line now transmission lines rusted out lesson learned. You're right I think it's just the rusted lines the angle I seen the leak made it hard to tell where it's leaking. I never mentioned that the trans fluid leaks on the catalyst converter & causes thick smoke in car & out ,But yes I will change out the lines next weekend or send it to the shop, wanted to replace mostly everything new before I send it for body work & painting . Thanks for the info and your reply
