    I just replaced my radiator on my 99 burban and am struggling with the transmission cooler line fitting leaking at the radiator. I'm using a fitted wrench (5/8) and I've tightened as much as I can but the fitting bolt is starting to strip.
    Any suggestion?

    If I recall those are normal inverted flare fittings. You must have a piece of debris in there. Pretty foolproof connection.
