I have a 2004 Z71 with push button 4wd with the auto 4wd button as well. Recently every time I start the truck, 4wd is engaged so have to switch to 2wd EVERY TIME! I am wondering why this is happening and what I need to do to fix it. No dtc's present and all buttons for the 4wd system working percectly . Please help

The truck also engages the 4wd system without any problems. Everything works as it should except for having to switch every time I start the truck

I'd take it to a shop that has a Tech II or equivalent scanner to check the encoder motor. The sensor on it tells the truck what position to be in may be going bad and not telling the truck the right thing. Also it could be the motor itself is going bad.

      I agree.   However, the owner's manual, suggests that a drop over full is just as bad as a drop under. (Read black and white letters only, insert no common sense.)

      Transmission Woes :-(

      By asilverblazer · Posted

      That P0700 and loss of power suggests something significant is amiss to me.   More/other codes may suggest otherwise; I would investigate those prior to spending the money to change fluid on a transmission with a bad torque converter.    The relatively sudden escalation of symptoms to me suggests that something began failing (initial shuddering experienced) and rapidly deteriorated (slipping/loss of power). Fluid condition alone wouldn't cause the sudden escalation of problems - though it might have been the cause of the deterioration up to the point of failure.

      AWD conversion to Z71

      By asilverblazer · Posted

      Stabilitrack operation is in a sense a separate/independent operation from the operation of 'traction control'. Stabilitrack is used to keep the vehicle traveling in the DIRECTION intended, it can brake independent wheels and or adjust throttle to influence the direction the vehicle is moving.   This can be illustrated by a 'fish-tailing' example. At high speeds, if the stabilitrack detects excessive yaw (the vehicle spinning like a top, it has a sensor for this), based on inputs from steering angle it determines that the vehicle is spinning out of control, and begins working to control that unintended spin. By reducing throttle input or braking specific wheels to control or prevent the spin.   The traction control works similarly using the ABS system to slow spinning wheels and thus transfer power to 'other' wheels. The goal being to achieve wheel speeds that are all in agreement with each other, the truck then assumes that since all the wheels speeds are the same no spinning is occurring. For example, launching up a wet boat ramp, there is no excessive yaw present, traction control alone can manage the wheel spin by braking spinning wheels and cutting throttle.   Stabilitrack and traction control from a hardware and software standpoint are basically one in the same, I don't remember specifically in 2004, but you couldn't get a truck with one and not the other. The switch on the dash, could turn off the traction control, but not necessarily the stabilitrack.    A confusing comment about stabilitrack vs. traction control, the same components serve both operations, but marketing could advertise them as two separate features.    The AWD system is another separate system entirely, in addition to the other two, it uses the same wheel speed inputs but can also vary the transfer case clutch application to direct some power to the front axle, working in conjunction with the traction control to bring wheel speeds together.   The power split will never be greater than 50:50, the same as 4-high. It will never direct MORE power to the front axle than the rear.

      Start-Stop ?

      Not based on the new photos I'm seeing.  Car and Driver posted additional photos that shows an auto stop start button left of the steering wheel.

      2027 Chevrolet Silverado: Official Discussion

      Car and Driver is reporting wireless CarPlay WILL remain, and they posted several additional photos, including a left knee shot, but the only hard buttons there are e-brake, auto start stop, tailgate and cargo light.  Also definitely looks like High Country and ZR2 get micro fiber on the center of the console lid and the ZR2 possibly also on the seats.
