2015 Manual Transfer Case Issues

[kolinlapage]

I have a 2015 Chevy Silverado Work Truck 4wd with the 5.3l V8. On my truck, I have a manual transfer case on the floor similar to older trucks. All of a sudden my 4wd light on the dash will come on and my truck starts whining and grinding like it wants to go into 4wd. My shifter for 4wd is positioned in the 2wd position, and the light is still on. I can put it into 4wd and then back into 2wd and the light will go off and 30-60 seconds later the 4wd light will be back on. Now even when I turn it on sometimes the 4wd light comes on immediately. Has anyone else had this problem? If so what did they do for repairs? Anything helps

Adjust the 4x4 shift lever under the truck.

Adjust the 4x4 shift lever under the truck. 

Have you got any more info on this? Mine has the opposite problem, very difficult to get into 4x4.

I dont have any specific instructions, you just need to crawl under there and watch the linkage move and see if it is binding, broken, etc.

The linkage is a good place to start. However, I would consider deadlining that truck, until you can get a real inspection and find a definitive cause. If you continue driving it as is, it might get expensive quickly. Just my .02

I was able to get the truck to the dealership and was told that I had a faulty transfer case switch. They replaced the part and haven't had a single issues with it since.

That's weird, I could understand that if the 4x4 light was just coming on but for it to be whining etc like it is shifting into 4x4 seems strange as that would require the lever or linkage to move.

Glad you are sorted anyway.
