Lately, I've been noticing that the transfer case selector will show the wrong selection at startup. I'll park the vehicle in 2Hi, but when I restart, it'll show either neutral or 4Lo (neutral is more frequent). Thing is, I've driven it before noticing that the display was incorrect, and the vehicle was indeed in 2Hi just like I left it, regardless of what's lit up. I mean, if the transfer case were actually in neutral, for instance, it wouldn't go anywhere...and you'd definitely notice 4Lo at highway speeds.. To get it to display 2Hi, I have to put the transmission in neutral before selecting 2Hi. If I leave it in Park or any other gear and try to select 2Hi, the 2Hi light will blink for about 10 seconds before giving up. Going from a transfer case display of Neutral to 2Hi is quick and quiet when the transmission is in neutral...switches right over. It's much more worrisome when it thinks it's in 4Lo, because when you put the transmission in Neutral and select 2Hi, it takes a few seconds then you get a pretty solid CLANK from the undercarriage before it switches. That clank scares me. Deeply. Afterall, the vehicle's not actually in 4Lo...it's in 2Hi...switching to 2Hi...what's there to clank? Anybody ever seen a problem like this before? Also, I have a check engine light issue. Seems to be independent of the transfer case stuff, because they don't necessarily happen at the same time...in fact, I don't think I've ever seen them happen at the same time. Anyway, I'll start the vehicle and the CEL will come on..then chimes..then a "REDUCED ENGINE POWER" message. If I try to drive it like that, it won't exceed 2K RPM...'limp in' mode. If I shut it off and restart, the CEL will stay on but the message goes away and the vehicle is back to full power. Typically, If I shut it off and restart once more, the CEL and message are both cleared and it's as if nothing ever happened. Anybody got a clue about what might be causing that? Thx in advance!
