Does anyone know how much the transfer case shift shaft turns or what direction to get into neutral? Is it a full turn or a fraction of one? I could not get it into neutral with the pushbuttons, so I replaced the encoder with it in 2-HI. Although, I did not have to turn the new encoder at all to make it fit in place of the old one, so I'm not sure if it's necessary to put the case in neutral. Anyone I still have the same issue switching between modes, but I'm not sure if it will still randomly switch when driving with the new encoder.

To be honest, it costs me less than half to replace the encoder ring than it is to have it scanned by a dealer. If I am wrong, then I still saved $55, since it can only be one other thing. On the other hand, I refuse to pay $100 to simply find out what's broken on my vehicle. There is no reason with todays technology that you should need a multi-thousand dollar calculator to recieve system errors/faults. Not only that, but it allows mechanics to falsley state what is wrong with your vehicle. rather than you knowing directly before you visit. It really should be illegal in this day and age. Imagine if Microsoft or Apple charged you $100 to display error codes on your computer or phone. There would be riots.

What did you do to fix it?

The issue I'm having is on a 2003 Silverado, 5.3 LS. Not long ago I had my PCM updated/reflashed and since then my 4wd-HI will randomly engage while I am moving at decent speeds. Once 4wd-HI engages, the only way I can get out of it is by going to AUTO then 2wd, but even then it will not work sometimes. When switching back does not work, I can feel 4wd-HI disengage from the front wheels, but the 2wd light will continue to blink and shortly after switch back to 4wd. It's been happening more often and I'm afraid it will one day switch to 4wd-LOW at high speeds and grenade my differential transfercase. I've read that it could be the control panel, but when it happens all the lights continue to work and I am not getting any dash 4x4 service message. The other is the encoder, but before I spend the money and time I'd like to get some more opinions from those more knowledgeable and experienced than me. Thanks
