I just swapped transmissions and now have a "slight" drip from the lower trans line fitting at radiator. I did not remove the lines from radiator for the swap but there was some movement in the lines while doing the swap but at the tranny end so it appears that fitting was disturbed from its former leak free self



I can't tighten it any more and understand the M & F flare ends are what make the seal.



I did a 1 wrap of Teflon tape on the thread and re-attached and it now is just a slight weep but will leave a drop after a drive.



Is there something like a rubber washer that is formed to mate between flare ends. Something like this pic?



or something else?

Seems like you're asking about the tranny line cooler connection of an A4 but your sig indicates M6/T56 ?
The A4 cooler line to the radiator uses an 'inverted flare' connection at the radiator.

Flare gaskets are available. IMO the worst idea ever. A good flare doesn't leak, You can weld (metaphorically) the flare fitting on and if the flare is bad it'll still leak.
If the fittings ar tight and it still leaks you need to cut and reflare it or replace the line.

I pulled the connection apart to confirm the flare on each side was not cracker or debris between them and pulled the tranny line so the line end now went in flush to the radiator and all is good now. The line got pulled back during the tranny swap enough to disturb the previously not leaking lower line

This is not on the car in my sig....its a 67 Camaro

Thanks
