Question about 2002 GMC Sierra 2500HD
I have a 04 gmc 1500 and when i am in gear and hit the gas i get a loud squeaking noise almost like a bird chirp. it will do it anytime i hit the gas but the harder i hit the gas the louder it is. . any answers please help
Your problem is similiar to mine . the web-site has been helpful. $2000.00 sounds way to much for repair on that vehicle with such high mileage. I went to a dismantler and bought a used transfer case for under $350.00. Did the labor myself with a little help. It's not too difficult if you have a some diy experience or ability. As your working on it stay with the web-site for install hints or go to autozone.com for repair diagrams.
Good luck have a good day.

I have the same problem. It is intermittent and sometimes shows up with service transmission message. To get rid of it just put the truck in park, press the 2 high button and shift into drive while it is still flashing. I will worry about it more when it blows up. You can drive with the vehicle showing the solid neutral and it seems to make no difference. It has to be a wake up problem between the control modules. It only happens on start up.

Sudden grinding noise with no prior warning * Primarily in 2nd
gear, behavior in reverse may be abnormal; sunshell is fractured.
R&R. Try not to run or drive the car or further damage could result.
* Reaction planetary is worn out due to high miles or insufficient lubrication. Not a critical failure, but not a good sign either. R&R sooner rather than later.
* Either a torrington bearing or a planetary bearing is on its way out. Trans will eventually die a loud, catastrophic death. Cheaper to rebuild now (saves further damage to hard parts), but requires R&R. It is drivable until it breaks.
Good luck and thank you for using fixya.
