    My trans cooler lines are starting to seep some. Does anyone know what the part numbers are for them? Or the best place to get them from? This is in a 2006 1500 Sierra with the 5.3L. Thanks.

    Don't get OEM replacements because I guarantee they will leak also as GM still can not make a proper crimp and a beefy hose to begin with.Lots of good info on the DP of how to fix yours or where to buy already made up lines depending on your mechanical abilities.To give you one option I used all flexible lines from a vendor there on my Allison.

    One of the guys I work with used to be a mechanic at a GM dealership. He is going to give me a hand changing them out. Thanks.

    Up to you but you will spend less money on aftermarket replacements that will not leak vs. OEM ones that are destined to leak,especially when it's cold out.

    That doesn't surprise me. I just need to find the right aftermarket lines.

    There are three lines, correct? I can only seem to find two.

    go to your parts store and get an aftermarket universal trans cooler. I just did this on my 02 with a 5.3. the aftermarket cooler i got was around 50$ and at least twice as big and just had slip on connections, so i just cut off the gm crap, slid the rubber on and clamped them on.

    it was tricky to get it to fit, i used a peice of 3/4in angle iron as a support which may have been overboard...

    I was thinking the lines might be the same. I just took my lines off my truck and took them to a local hydraulic place and they fixed them for me, Was a lot cheaper then Tony also.
