These vehicles have an issue with the transmission cooler lines leaking at the crimp (that connects the rubber hose to the hard steel line). You can replace the lines but they will leak again, usually after a season of cold weather.
I used a dremel to score the aluminum crimp, slid a screwdriver into the cut and twisted. Managed to spread it enough to remove the crimp and pull the rubber hose off. Did it for all 4 crimps, pulled off the rubber hose and replaced with new 3/8" tranny cooler hose. If you're careful when cutting and don't go too deep, it'll leave the OEM barbed fitting and shoulder in place and you can slide the new hose on there. Used fuel injection hose clamps to seal back together.
