'08 Denali XL Transmission Cooler Line Replacement

Eismann95 · Mar 13, 2018

So, the Stealership wants $809 to replace 3 trans cooler lines. WTAF!?! I can only find one line on CarID and RockAuto. What am I missing? I know the fuel line/double hose clamp fix, but if the lines are more gone than that, I'd do full replacement. Does anyone know the line part numbers?

I don’t know your part numbers, but i just replaced mine only 2, no external hd cooler and it took about 2 hours. Not hard but takes a little finesse getting them in and out.

I had to do my upper trans lines as well last month. It was a little less than that but still pricey. I'm not sure where they got the replacement lines for it, but they had them within a day. I think they came from the local parts store.mine supposedly weren't as hard as a 2008 Tahoe he and just done a couple days before but still took home a few hours.

there are 2 listed on rockauto-however, 1 of the 2 part numbers is actually 2 lines
grand total of about $70
