    Noticed this morning that my 07 Chevy 2500hd has a couple drops of tranny fluid on the pavement. Took a peak underneath and it looks like one of the lines is eaking at the crip, where the aluminum meets the rubber. Its been colder than hell las t night well below zero, so i'm sure that may have something to do with it. We got snow coming in tomorrow night and nobody stocks these in my area. Chevy dealer can get me in monday afternoon but that doesn't do me any good for plowing snow Sunday night. My question is should I not use the truck until this is fixed or would it be ok to plow with it? My gut feeling is not to use it but i'm not a mechanic.

    Welcome to the infamous GM crappy tranny lines crimp club.They ALL leak.GM knows about it too and they have their ''new and improved'' version out but trust me--DO NOT GET IT. 1 or all 3 lines,doesn't matter,they are still leakers as GM has only slightly improved the crimp design.Yes,you are right,the cold weather will make them weep more,mine was a weeper for over a year.You will usually be fine,there have been extremely few that have had a line actually blow apart.There are SEVERAL ways to fix the problem but for app. $150 I solved mine by throwing all 3 lines out and getting all flexible hydraulic lines from Red's Auto Rehab on Ebay. Money well spent,4 hours for the install and my parking space has been bone dry for 2 months now. PM me if you want for more details.

    Good to hear. I'm just a little paranoid, I wouldn't want tthat thing to burst and not know about until its too late. My '99 had to have the cooler lines replaced but they leaked up at the couplers. I don't think there is a gauge that even tells you when its low is there, mine doesn't have a temp gauge. Send me a pm about those lines, mine is not a Duramax so do they make those for the 6.0?

    You can ask Red the question on Ebay,but he only has the 3 piece kit for the Allison advertised.You can go to a reputable hydraulic repair shop and either have them fab up complete new 1 piece hydraulic lines or they can cut out your rubber section and put a new heavier short hydraulic hose using either flare,compression,silver soldered in fittings, or AN type fittings to connect to your solid tubing lines. Whatever you decide,change all of your lines that have the crimps as they will eventually all leak.Not sure exactly what you have there.

    Dealer mechanic says both are leaking, so i orderd them both. They say the job takes 3.5hrs and total for the job will be $550. Has anyone changed these out themselves on a 6.0? I was thinking about having my uncle do it as he used to be a mechanic. Dealer says the bumper has to come off, quite frankly I can't see why. They also said that you lose alot of tranny fluid, how much should I have on hand to do this ourselves? Any help would be apreciated.

    I just had both lines on my 01 2500HD done and it was like 220 parts and labor. I would shop around.

    Your new lines will leak also.Whether it's the Allison or another GM tranny,doesn't matter,ALL those GM crimps are absolute garbage.And I would stay far far away from that stealer--the bumper does not need to come off and you will only lose app. 2 qts. of ATF.Why don't you PM B&B for how he repairs those leaky lines by cutting out that factory rubber line and retro fitting all new hardware and flex lines.

    No way does the bumper need to come off. The grill yes, bumper no. I got the gm lines and they ran me about 70 bucks total for all 3. Took me a lil over an hour and a couple beers in my driveway.

    Thanks guys. Now I really feel like I'm getting hosed by the dealer. We will definately be doing this ourselves. I can't see how they figure 3.5 -4 hrs in labor, doesn't add up to me. I'm going to check into getting the flex lines replaced with hydraulic hoses and fittings. WTF doesn't GM do this from the start? Thanks for the info.

    Ha ha.
    Have you tried Napa, Factory Motor Parts, or Rock Auto. You can do them yourself, you will cuss a little but should take you no more than 2hrs doing it on your back if you have access to a hoist it's pretty quick

    I tried Oreily's, they said it was a delaer part and they can't get them. I ordered the parts through GM. I'm going to take the old ones and try to find a hydraulic shop that can put in new flex lines and keep these for the next time for a spare set. We don't have a decent hyraulic shop close by that I know of so, I'll have to do some checking.

    Had lines replaced on my 07 3500HD Dmax a few months ago. Dealer charged about $600. After reading this I guess they'll be leaking again in the future. Sure won't go to the dealer nextime.

    You couldn't get a 3500HD in 07'. It bugs me when everyone calls everything a HD

    Sorry buddy, but you're wrong. The '07 "Classic" was 3500. The '07 "New Body Style" is 3500HD, it's displayed on both doors, and I did get one. Just calling it what it is to be accurate on here.

    We changed mine last saturday took about 2 hrs I think. The hardest part was trying to find one clip when it popped out. lol Discovered that the engine cooler line is leaking, at the crimp. :realmad: Its going to have to wait though.

    Let's see,go get another factory new POS line that will not leak for awhile or go to the aftermarket or fab up some nice hydraulic lines that will most likely never leak and are cheaper priced than factory and will take app. the same amount of time for the install.:confused:
