lq9crew Posted March 15, 2008 Report Share Posted March 15, 2008 I need help!!!!! My truck went to the dealer to fix a leaky trans. They had it two days. I start it up the next morning when cold and hear an exhuast leak. I crawl under to see this. WTF were they thinking? I need a picture of this area, the way this left the factory so I can get it fixed correctly with as little trouble as possible. I'm afraid of going in, and their repair will be torqueing the clamp down making it impossible for me to separate these two pipes in the future. If anyone has a picture, a parts diagram, a part number, anything to help me, I will be truely grateful!!!!!!! PLEASE HELP!! P.S. Truck is a 2006 Sierra, 1500, crew cab, 4x4, 6.0L, 4L70E, 4.10's, 9.5" 14 bolt rear. I think the HD's have a similar exhaust setup as well as the Sierra Denali and the Silverado SS.

detjoe Posted March 16, 2008 Report Share Posted March 16, 2008 the correct clam is a band type that is tack welded to the pipe. this is strange. the heat shield looks damaged too. keep us posted, tell them those clamps dont seal, and its gonna leak again.

YenkoChevelle69 Posted March 17, 2008 Report Share Posted March 17, 2008 I personally do not think that that clamp is causing a leak. Guess I could be wrong tho. Quote Link to comment Share on other sites More sharing options...
lq9crew Posted March 17, 2008 Author Report Share Posted March 17, 2008 Just returned from dealer. I talked with the service manager and showed him the correct picture (Thanks again Mike!) and the picture of the work that was performed at his dealer. The manager told me the clamp in question is the approved replacement type and there is no "band clamp" available from GM. I told him I would not be satisfied and would do whatever it takes to get it returned to factory specs. (Who do you report to?) He disappeared while I talked with the service advisor and came back to tell me he found an aftermarket clamp, and would order it today and install at my convenience. I'll wait until I see this clamp before I decide if this issue is over or not. Quote Link to comment Share on other sites More sharing options...
YenkoChevelle69 Posted March 17, 2008 Report Share Posted March 17, 2008 I think is tho, that this band is welded in one spot to the exhaust. Try for a new exhaust LOL Quote Link to comment Share on other sites More sharing options...
detjoe Posted March 17, 2008 Report Share Posted March 17, 2008 I used an air hammer and reused mine on my corsa. Pissed off the negibors real good using the loud ass air chisel on a pipe @ 7am...but hey I needed to hear my corsa. Quote Link to comment Share on other sites More sharing options...
Vortec MAX Posted March 18, 2008 Report Share Posted March 18, 2008 I never thought to ask, but why would they mess with the clamp to fix a tranny leak anyway? And what caused that burnt spot...a torch? Mike Quote Link to comment Share on other sites More sharing options...
