Hey guys, first time posting not sure if I'm posting in the right spot. Having a 4X4 concern.
2004 GMC sierra 2500DMAX push button 4X4 rpo NV1 transfer case NP263 (not automatic). Push the 4hi button goes in no issues, push 4lo goes in no issues, when you push 2 wheel drive button to get out of 4lo it will sometimes stick in 4lo. Shut truck off, wait a few mins, push 2 wheel drive button and it will go in. Pulled faults with tech 2 and got B0790-transfer case neutral indicator circuit malfunction and B2725- mode switch circuit malfunction. Any known issues for this? I've heard encoder motor a few times not sure though. Any help would be much appreciated. Thanks
