Transfer Case Problems of GMC Sierra
GMC Sierra owners have reported 11 problems related to transfer case (under the power train category).
#1 - Transfer Case problem of the 2004 GMC Sierra
The vehicle having this issue was a 2004 GMC Sierra. The manual shift on the fly system (msof) with new venture gears automatic transfer case is defectively designed. A metal anti-rattle clip works it way through the case housing, causing all fluid to leak out of the transfer case. The clutches then burn out rendering the transfer case useless. The result is no 4 wheel drive (no power to front wheels) when shift on the fly is pressed, leaving driver sliding on snow or ice--which happened to me in a near wreck. I recovered from the slide and got the vehicle home and then to a repair shop (once the snow melted) for a new transfer case (repair ongoing). Drivers may rely on the 4wd in inclement weather to certain conditions and be injured when the 4wd does not engage due to the defective transfer case. This transfer case issue occurred March 1, 2012.. Read more...

#3 - Transfer Case problem of the 2004 GMC Sierra
The VIN of this vehicle is 2GTEK19T74_. I purchased my 2004 GMC Sierra 1500 4x4. I put it in 4 wheel drive to go through some ice and it made a very loud clank. Not long after that when I put it in reverse or drive it also made the same loud clank. It did not sound like that when I first bought the truck. Now the truck has trouble going into 4 wheel drive and also gets hung in reverse. It has almost caused me to get in a bad accident. My cruise control also has have 6 malfunctions. I had the dealer fix it initially. I have fixed it subsequently due to the fact they said it was a blown fuse. The 4 wheel drive and transmission problems were addressed 3 times and all the dealers said nothing was wrong. An independent mechanic said there is a defect with my transmission and transfer case. That is it with the truck. Now just last Thursday Feb 3, my bridgestone tire separated. My tire dealer said the tire was defective. There was no evidence what so ever that there was any damage to the tire to cause the blowout. It should not have separated. It caused a fire. It was quickly put out. It was Oct. 4, 2004 when this transfer case issue happened.
#4 - Transfer Case problem of the 2003 GMC Sierra
The vehicle identification number (VIN) is 2GTEK19T23_. I have a 2003 GMC Sierra slt ext. Cab z71 (4x4), the 4-wheel drive is not working, no lights show up on the buttons. The dealer has attempted to replace the 4wd switch, this did not fix the problem, they still have the truck. The truck is less than a year old and has 20,700mi. There are service bullitens for the problem, but there is no permanent fix. Why sell a 4wd product if the 4wd will not work?. This transfer case issue occurred Sunday, August 3, 2003.

#10 - Transfer Case problem of the 2001 GMC Sierra
I own a 2001 GMC Sierra. I noticed that when I put my truck in 4 low on my 4x4 (manual shift),and I put the truck in reverse, you can feel the torque. When I go and put the truck into park it starts to grind while engaging in the park position. I brought it to a GMC dealership and they told me that it is normal for the transfer case to do this. If you ask me, if there is grinding noises on moving parts, something is not right or "normal". This transfer case problem happened on Mon., Sep. 12, 2005.
