This 'new' (to us) 03 has a leak at the fitting where the trans line attaches to the fitting at the radiator. It's a v8 H.O. and it's the top tranny line fitting. Previous owner had a shop put in a new radiator not long before selling. The shop did a crappy job and there were leaks all over the place. I got the other leaks stopped, but this one. I tightened the fitting which slowed it some, but didn't stop it. I know for sure it's not where the fitting attaches to the radiator.

Does the line have a flared end, or is there an o-ring there?

Thanks

 

I'm pretty sure it's a 0-ring seal type, similar to the fuel line. IDK for sure.
