The Top Transmission line on my radiator on my 1987 Grand marquis is leaking is there and way I can fit it

If it is leakind at the radiator fitting....Have you tried to carefully tighten the fitting? You may have to replace the fitting which should be available at most autoparts stores such as O'reilly Auto Parts or similar.

The part number is likely 800-609 and the brand is Dorman. It is less than $10.00. http://www.rbinc.com/p-20647-800-609.aspx

Hey bob the plastic fitting on the transmission line that twist into the radiator it broke

That fitting is threaded into the radiator. If the threads within the radiator are bad you may need to replace the radiator.

The transmission line is bad the radiator is brand new

It's the black piece

Thanks Tom

The Dorman number I looked up was from the Dorman website. Regardless of the part number the part is readily available and easy to replace.
