Default 2006 hummer h3

I need to replace a transmission cooler line, are both lines the same? Or do I need to order the specific one?

Save the cost. My gf's H3 needed them and we purchased them at her stealer ship (actually they were decent with her discount) and had a third party shop install them both. They were stupid costly lol!
I just decided to go on Amazon and by the correct diameter trans line (the rubber black braided kind ) and made the new lines. Cut each oem line (leaving enough to flare) and then use quality hose clamps and zip ties. Your done! I think I spent a few hours and maybe 50-75 for supplies if that.

No both lines are NOT the same. There is an Inlet Line and Outlet line. You can order factory type replacements or go the make your own line route, up to you. I would suggest you do the work if you are able.

The outlet #5 PN15196327 is like $26. The inlet is #1 is harder to find PN# 20788329 but still only $21. Never buy anything at any Dealership unless and only if they are an online GM Parts Outlet where you can order online and pick it up free shipping.
