    Was replacing the condenser and radiator and I twisted the tranny cooler lines and now they're both dripping tranny fluid. They were wet before I even touched the radiator.

    Auto zone and o Reilly's only have the lower line. I need both. Should I call the dealer?

    i pulled the junk radiator up with the lines still attached so I could unhook them from the radiator. after that I held the lines against the front of the engine as i was replacing the radiator and condenser. they are horribly rusty. i think ac delco # 10330106 is the line i need not sure. i need the upper cooler line. all the parts stores around sell just the lower line and i need both

    They rust out just like the fuel and brake lines, I would replace them.
