    Transmission Cooling Lines Leaking

    I have a 2007 Silverado Classic 1500 Crew Cab with 69000 miles on it. When getting it inspected I was told that the transmission lines were leaking. I brought it into the dealer and they told me that 3 of the cooling lines were leaking at the clamps and all 3 lines needed to be replaced. The did so for $634!!! Apparently, these lines are not included in the limited powertrain warrantee. I contacted GM and they had a local representative contact me and he confirmed that they were not included in the warrantee. When I challenged him with the fact that the warrantee specifically states that "seals and gaskets" are covered and it does NOT state that "internal" seals and gaskets are only covered the GM Rep was rendered stuttering and speachless. I asked him to esclate within his management. He called me back and said there was nothing he could do. When I asked who he escalated to he said it was "confidential". One thing he did offer me was $1000 off the purchase of a new GM if purchased within the next 12 months!!! Are you kidding me? Let me get this straight.....I have a GM product that has problems and customer service has been poor.....now you want to give me an incentive to purchase another???? Why not just give me the $634 for the repair and we'll all be happy?????

    Does anyone know contact information for GM executive management? Specifically, Jim Campbell - the GM of Chevrolet?

    Re: Transmission Cooling Lines Leaking

    I had the same problem with my cooler lines, 2003 Sierra, but I also own a transmission shop. The truck had 78,000 km on it and they wouldn't cover it at all. The crimps leak at the rad, I see this alot normally I just cut the line flare it and reclamp it with no problems but this truck was not old and under warranty after complaining I just repaired it my self. I will never trust GM and there warranties again. Dodge will be my next truck I've never had a problem with warranty on my jeep, they just fix it.

    How can a few hose clamps + labor cost $634? Did they have to pull the trans or something?

    $90 for parts and $544 for labor. And no, did not have to pull the tranny.

    My reply to the GMI staff member who states "physical external lines are not "seals & gaskets" so I don't see the end of the arguement there...." Read your "Limited Powertrain Warrantee" which states as being covered "Transmission/Tranaxle/Transfer Case, all internal lubricated parts, torque converter, transfer case, transmission/transaxle mounts, seals, and gaskets" Whether the cooling lines are external or not, they do have seals on each end which are meant to maintain the proper fluid level to lubricate the internal parts. Had I let these seals continue to leak, GM would be replacing my transmission under th warrantee. For sake of argument, "mounts" are external to the transmission as well however they are covered?????

    Re: Transmission Cooling Lines Leaking

    I'm definitely in no mood for a pissing match either. At least your explaination is far more than I got from the region GM rep that contacted me via phone. Yes, I do have 69K miles which on GM's foreign competitor vehicles isn't even broken in, let alone broken! I try so hard to keep the buy american spirit but unfortunately the american companies don't seem to give a crap. I had a 2003 Sierra that had a clunking noise when shifting from 2nd to 3rd gear (auto trans) almost from the day I purchased the vehicle. After 5 times of bringing it to the GM dealer and hearing that there was "no problem found", I decided to just deal with it. And believe it or not.....My 2007 has the same clunking noise.

    GMCSonoma......Thank you for posting the time to replace the 3 lines - 2.1 hours. My only question on that would be does that factor in draining the fluid and refilling. Just wondering before I get on the phone with the dealer that serviced my vehicle.

    Well. I just got off the phone with the service manager where I brought my vehicle. She indicates that the 3 lines individually would be 1.7; 1.2; and 1.3 hours for a total of 4.2 hours at $98 per hour $411.60. Apparently the add the diagnostic fee on top of that! How would your SI give you 2.1 and theirs 4.2?

    givin all the attention to your foreign competitor I would not go there right now...

    anyhow shop rates will vary....our 'book' here says 3.5 hours to do all 3 lines @ $103 per hour, I was also told any decent mech should be able to do it in 2 hours give or take a few minutes for 'crap'...as for parts I did not look up the parts price for the hoses.

    and yes GMPP is worth its weight in gold......covers almost everything on your vehicle, I have seen it save people lives literally. One thing I will promise ya is they all break, even the other guys......

    diagnostic fee?? confused here I am under the impression this only applies if they need to plug a tech 2 into it, this can bee seen pretty easily so what is the diag time....20 seconds.....

    One other note I will pass along, GM at least here has a bullitin on this, they knowits a problem and have sent new lines but wont recall it or warranty it, almost ALL 07 hafl tons I have sold have come back for this.....my brothers 2 times

    Almost sounds like they gave you the labor guide times from the 2500/3500 allison bulletin:

    Transmission Fluid Aux Cooler Inlet Hose - Replace
    1.7 hrs

    Add
    To Replace Lower Pipe if Required
    0.2 hr

    Transmission Fluid Cooler Upper Pipe Assembly - Replace
    2.3 hrs

    Add
    To Replace Lower Pipe if Required
    0.2 hr

    Add
    To Replace Aux Cooler Hose if Required
    0.2 hr

    Add
    With 4WD
    0.6 hr

    Transmission Fluid Cooler Lower Pipe Assembly - Replace
    1.5 hrs

    The only line replacement bulletin there is is for the Allison/dmax trucks. There is a fitting replacement for 1997-2008 4L60-70 trannies #08-07-30-004


    Now that I read the first post again, it sounds like that it might have been just the fittings that needed to be changed (the bulletin above).

    Re: Transmission Cooling Lines Leaking

    Thank you everyone for your posts and suggestions. As it turns out, I called another Chevy dealer in my area and requested a quote. I was told total job would be around $400 plus tax. Total laber time was estimated at 2.7 hours. Armed with this quote, I went back to my dealer and asked WTF. We are currently working towards an amicable solution.

    Try a indy shop......................
    I use a local one for all non warranty repairs on my vehicles.
    The charge $50 per hour labor rate and don't "charge to look" either.

    Since its only leaking............But yet agaIN I see many posts of leaking
    and troublesome trans. lines in the GM truck forums.

    Thanks everyone for your posts/comments. After discussing my situation with the sales manager, it was determined that I was in fact overcharged for the work. They issued me a partial refund and we're all happy now. Thanks again everyone.

    Score one for the consumer and some of the helpful folks that post here!


    To clarify my previous post...............The leaking lines I mentioned are not the steel line itself leaking but the POS crimped/connectors that are the issue.

    Unlike the line connectors of old that were actual metal flared lines with steel nut connectors that screwed together or screwed into the radiator/trans./oil cooler etc.....................
