Recently lost my 4WD when shifting it from 2WD to 4WD. I have electronic shift dial on the dash. I've replaced front diff Encoder motor, T-case Shift motor. Last week after I swapped the Tcase motor the 4WD worked again for about 2 days. Now its out again. Ran codes on it today at Oreilly's and its got CO 387 and CO 374. Looks like the 374 is a 4WD speed Sensor? and that failing is throwing the other code 387? Any ideas on what the root cause would be?

Hello everyone, I have an issue this morning with my z71. I loaded my truck down with house hold garbage.. Turned on the truck no issue that I noticed ( Havent started the truck in a week) Got in to drive then noticed all the lights on the 4wd selector on the dash were lit and the service 4wd was reporting on the dash console. I unhocked the battery for 5 mins and tested again, same issues. Hooked up tester ODB2 no errors. Can anyone help me with this? Any advice?

So, yesterday afternoon, I jump in my tuck after running errands. service notice flashes says "service 4wd" I dis miss this, check my 4wd knob and its in AWD, where it stays unless I need 4wd. I go to back up and turn and its clear Im in 4wd. Cannot get it out of 4wd. Tried running through 2wd/4hi/4lo etc. nothing no shifting at all. I drive a lot so my truck is at about 54K (its a 2015, bought in 2015) and I have had no issue with it so far. great truck. no complaints. So, I drive into town today, call the dealership (who at first said they couldn't look at it till Tues- wed) they eventually say they can squeeze me in today around 2. Great! I think this is great. Still under warranty, if it has to be messed up better now then in 6k more miles right!- but wait. looking up their warranty the most likely culprits (wiring, tccm etc) aren't covered under warranty. Really. with so many others having this problem?... I can accelerate and drive it, turns are irritating. Seeing that there aren't any real "fixes" for this since 2014 not a good start to this week. Anyone find anything that seems to have stopped this action from reoccurring?
