Hello Anthony,

I apologize, but I am not an engineer or a technician, so I would not be able to address any technical questions you asked. If you are experiencing a concern with your transfer case in your Sierra, I would be more than happy to assist you in setting up an appointment with your dealership to look further into your concern. Please feel free to private message me if you would like any assistance setting up an appointment or working with the dealership.

check the bolts attaching the drivetrain(?) to the transfer case. mine were way loose. and the fluid in the transfer case is supposed to be plain tranny fluid. at least thats true on a 1990 Sierra.
