2005 SS Just got done replacing radiator myself, pulling cooling fans, etc. All because of that lower tranny cooler tube that inserts itself into the radiator fitting (the fitting was broken). Bad design...I will be taking the time to add a tranny cooler by-passing the radiator soon. At least if one fails I am not replacing both. If anyone needs to know any steps or what I had to pull let me know; the repair manual I bought from Amazon (Haynes) didn't have anything covering step by step what to pull so do not waste your money on that.
