hello everyone

I am new to the forum and i was wondering if anyone is able to help me with my 2009 chevy trailblazer. I have a 4.2 liter 6 cyclinder engine with a 4x4 transfer case RPO NP8. I just recently had a check engine light on with an error code P2771. I did some research and i've changed the transfer case actualator motor part # 89059275 and still having the same issue. Can anyone guide me on what to do or check next. My car is out of warrenty and am trying to do as much as i can on my own.:(

According to the research I did, the problem could be either the Transfer Case Control Module (TCCM) or wiring between the TCCM and the PCM. You may need someone with a high-end scan tool and knowlwedge of the 4WD system to diagnose this.
You may also want to visit G M T N a t i o n .c o m to find more knowledgeable people.
