    Does anyone have the part numbers for the transmission cooler lines that go from the transmission to the radiator? This is what I have; ACDelco 15809053 for 1 line, don't have the second line part number.

    I think they are both the same but you can call a gm dealer to find out for sure

    Mine is leaking at one of the crimps on the radiator which sucks

    I replaced my oil cooler lines with Doormans they started leaking just out of warranty. I used a pipe cutter and a pair of wire cutting pliers to separate the crimp from the rubber hose. I then used a screw type radiator clamp to replace the aluminium crimp that I cut off, no more leak and works like a charm. Just like the pictures posted in post #7.

    I may do that so I don't have to worry about as the top one is leaking on my 03(could be the radiator as its needing replacing)
