    Transmission cooler lines *need quick advise*

    I found a leak in one of the transmission cooler lines and it looks like it's coming from the hose section. I'm going to replace them both and wanted to know if this was going to be difficult or easy and if there is anything I need to do to the fittings to prevent leaks. Quick replies would be greatly appreciated since I'm gonna try and do them tomorrow night. Thanks!

    Well, it looks like is coming from where the hard line attaches to the hose section @ the crimped section. figure I'll just replace the whole thing. Parts are fairly inexpensive.

    what about buying an AN line? and just replacing hte whole thing while your at it with something that will last a while? i know factory lines usually last forever, but they can easily get cut or pinched

    Are there any tricks I need to know about these lines? I've read stuff about clips. Aren't both fitting screw type?
