Default Trans line leaking at radiator.

Does the trans line on my Z51 where it goes into the radiator seal with a gasket or O-ring , or is it a pressure type fitting??. Mine is leaving a few drops of fluid once in awhile, and it's coming from that connection .....WW

Radiator side is basically one of these. Has an o-ring and a clip to hold the male side (from transmission) in place

The fitting itself screws into the radiator. There's an o-ring on that side too (picture is of a different model)

Could be leaking from either connection IMO

Thanks for the info.... Now I just hope it's one of the o-rings and not a fitting ..Would you think a parts store would have the o-rings ,or just a dealer? .WW

I'd probably just replace the whole thing if I was going to mess with it

I don't know the exact part number but it's very similar to this (if not this)

I went to the dealer today, and the only way you can fix this is if you get the whole connecter kit.. They dont sell just the o-ring... thanks for the help......WW
