Customer Question
2004 GMC Sierra 4wd...

2004 GMC Sierra 4wd, transfer case shifting into 4 wd low on its own. Tires lock up, truck skids to a stop. You can then hear the transfer case shifting motor operating.

Mechanic's Assistant: How old is the transmission? Have you noticed any leaking?

The top half cover of transfer case was replaced by dealer due to the recall for internal wear resulting in a hole. All original equipment. no leaks

Mechanic's Assistant: Are you fixing your Sierra yourself? What have you tried so far?

Hello
GMC Mechanic: Dan, Technician replied 5 months ago

It sounds like the transfer case shift forks may be worn out allowing transfer case to slip into gear. Unplug electrical connectors on transfer case to see if problem still happens if so this verifies problem is mechanical meaning transfer case needs to be replaced. In this case I'd tell dealer you think transfer case should be replaced for free or at low costs since recall wasn't issued soon enough leading to complete failure. Let me know if you have more questions, thanks .
