#1454 of 1492 Whining/Steam teapot noise by alexm234 Jul 14, 2006 (12:46 pm)
I have a 2005 Sierra 2500HD. It has been making this whistling teapot type noise comming from the engine area. You can only hear it when the vehicle is in any of the drive postions. If I put it in park neutral or reverse, they noise goes away. It also seems to get louder as it idles and the HD transmission gets hotter. Anyone have any solutions or idea of what it might be? Thanks.

#1457 of 1492 Looking at 2006 Sierra 1500 - New by pekknett Jul 17, 2006 (10:32 am)
Is this truck worth looking at, considering long term ownership? I have a 1997 Sierra 1500 and the repairs have gone through the roof!!!

#1460 of 1492 Reorganization by kcram HOST Aug 05, 2006 (4:46 pm)
Hi folks   In an effort to make things a bit easier to research, we're adding more focused discussions for the Silverado/Sierra so that they don't get lost in one general discussion.   If you click on the main Silverado & Sierra Group, you will see a bunch of new discussions broken down by specific sections of the truck. We'd like you to start posting your problems under those new discussions, and hopefully you can get faster respoinses by those who may be more knowledgeable about those specific areas.   Thanks! kcram - Pickups Host

Replying to: goldsmde (Jun 04, 2006 12:03 pm) I have a 2003 GMC 1500 Z-71 and at 60,000 miles my speedometer did the exact same thing and then finally froze up pegged at it's max. It cost me $1,100 for the dealership to replace the entire instrument cluster. Now a friend of mines 2004 GMC Envoy is doing the same thing at 55,000 miles. Is it too much to expect the speedometer to to work? Let's just say neither of us are happy campers.
#1462 of 1492 Re: Serious shift problem [inkd] by psmitty Aug 19, 2006 (3:50 pm)
Replying to: inkd (Jul 09, 2006 12:25 pm) I was having problems with my 2000 GMC Sierra 1500 4x4 with the 5.3 engine. At times the engine would not accelerate past 1800 rpm's, the engine had poor performance, and the transmission was slipping. I recently had my truck to a GM garage, and after some research, the problems appear to have been solved. General Motors has a technical service bulletin out concerning aftermarket oil charged air filters, such as K&N. If too much oil is put onto the filter when it is recharged, some oil can transfer to the Mass Air Flow Sensor, and cause it not to work properly. Hard to believe, but true. The bulletin describes everything, including transmission slippage. A new MAF Sensor ($215) and my truck runs perfectly again. The GM mechanic was surprised that a MAF Sensor could cause improper transmission shifts. At no time did the vehicle computer show any codes for these problems. While driving the vehicle with GM's Tech 2 plugged into the computer port, there were improper readings on the O2 sensors in the manifolds, but these cleared up after the new MAF sensor was installed. Hope this helps.
#1463 of 1492 key won't dis-engage engine by kingfishingirl Aug 24, 2006 (10:37 am)
okay, so this is my first post on this forum.... but after reading all the other potential problems i'll have with my sierra truck, this won't be my last. i have a 2000 gmc sierra 2wd v8 4.8... i can't find a chiltons, haynes OR helm manual for it and the local dealers here are putzes. i put my key in the ignition and after starting the truck, it would not dis-engage. i had to put the relays to stall the engine so my starter wouldn't be destroyed but even when i can shift into and drive in other gears and back into park... the key will not spring back out of the forward position. i haven't see nthis as a common problem, judging by the other posts here, so i figured one of yas might know how i can get my hands on a manual so i don't tear up my steering column. i have to go get a few parts after work, and all i have seen are a few screws under the steering column... please tell me there is nothing complicated in there. i am either changing the shifting cable or the ignition switch, hopefully the latter of the two... any thoughts? thanks nikki Replies to this message: kingfishingirl (Sep 01, 2006 9:35 am) kcram (Sep 02, 2006 1:57 pm) kingfishingirl (Sep 05, 2006 3:45 am)
