Replying to: jasminec (Jul 03, 2006 7:04 am) How many miles are on the vehicle? What kind of transmission fluid did they use? They may have used the wrong type of fluid for your vehicle. Find out exactly what fluid they used and make sure it meets GM specs. Good luck!
#1446 of 1492 Re: Michelin Tires [shiftless] by gmctruck Jul 03, 2006 (7:53 pm)
Replying to: shiftless (May 22, 2006 5:22 pm) I don't know if you bought new tires yet, but check the door sticker on your truck to make sure they sell you the correct tire designed for your vehicle. I originally purchased the Michelin LTX M/S tires for my truck, but it felt like I was riding on under inflated balloons! The Michelins were "P" rated tires(35psi max), but my door sticker called out "LT" tires which are rated for 50psi. You can put "LT" rated tires on a "P" rated truck, but you can't put "P" rated tires on a truck with an "LT" rating. The tire shop failed to check the door label before installing the "P" rated tires on my truck. I called the Michelin support line and was told the tires had to come off my truck because it was not rated for "P" series tires. I now have the "LT" rated Bridgestone Revo's which seem to be decent tires so far. I have the 265's which are a bit smaller than the 285's.
#1447 of 1492 Weird Whine Front of Engine by jonnycanuk Jul 05, 2006 (10:57 am)
I have a 1999 GMC Sierra 5.3 l 4wd a/c etc.. Overall an excellent truck that I use for towing. The last year or so it has developed an intermittent whine from the front of the engine. Sounds like the water pump but that fix did not work. New belt did not work. Of course whenever I take it in for servicing the sound goes away. A/c or or off does not matter.   Anyone else have this problem? What was the fix?   Anyone tried to buy a PS hose for this vehicle? This aftermarket part does not exist up here in Canada...and GM wnats in the $300 range. (I have a very very small weep in the hose and that is the next repair that is planned) Replies to this message: gmctruck (Jul 06, 2006 5:59 pm)
#1448 of 1492 Rising Transmission Temperature by cgood1 Jul 05, 2006 (2:35 pm)
I have a 99 GMC 2500 4x4 w/6L vortec and the transmission temperature is running on the notch between 40 & 95, i'm just curious if that's normal or if there's a problem. I reciently changed the fluid and filter with no change to the temp. There's 145km on the truck. Can anyone tell me what their's runs at? Replies to this message: pathy58 (Jul 17, 2006 12:30 pm)

Replying to: jonnycanuk (Jul 05, 2006 10:57 am) Check the serpentine belt tensioner.... they do wear out over time. You can buy a cheap(>$5)stethoscope that works well tracking down noise sources like yours. Putting your ear next to a long crowbar or screwdriver also works, but not as good, and is a bit more dangerous. 8-)
#1450 of 1492 Serious shift problem by inkd Jul 09, 2006 (12:25 pm)
First off, thank you in advance for any help or insight you can provide. I have a 2000 sierra 2500 series that is not a hd with 140 000km. The problem that is occurring is when you first start the truck or restart it warm. Basically when you go to give it gas, the engine will not rev up much if at all and will not let you accelerate at all. It does not feel like the transmission is slipping, it just feels like their is a limiter in place however is goes back to normal as soon as it hits second. The only code error that has ever came up was an o2 sensor but happened at a totally different time.   Again any help would be appreciated. Replies to this message: psmitty (Aug 19, 2006 3:50 pm)
#1451 of 1492 2-3 shift solinoid by eklund1 Jul 09, 2006 (1:37 pm)
I have a problem with the transmission in my 1500 4x4 5.3L Z71 GMC. The code says its the 2-3 shift solenoid. Has anyone had problems with this before? Is this a common problem? The problem started after having the tranny flushed and the filter changed. The mechanic said he pulled the pan back off to make sure he didn't smash any wires, and everything looked good. I will change out the solenoid sometime this week. My truck acts like its stuck in third gear. Its real sluggish when I start driving until I get up in speed and it won't shift into overdrive. You can manuely shift it just fine. My truck only has 87000 miles on it.
#1452 of 1492 2001 2500HD Alternator Delayed Start? by bigbilly Jul 09, 2006 (5:19 pm)
I have a 2001 2500HD Dmax, when I start the truck in the morning the alternator takes 30 -45 seconds before its charging at 14 volts. You can see the battery voltmeter sitting 12 volts then the jump to 14. Never seen this before on my previous trucks. Any ideas?   Thanks

#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.
