1. Truck gets stuck in 4 wheel drive with the light going off.

2. Truck quit downshifting hard as I had talked about previously but now it's back downshifting hard.

3. Sounds like a chirp after I turn my truck off.. 30000 miles should belt need change?

Anyone have any answers? Thanks for the help

It might be time for a trip to the dealer for warranty. I recall they did an updated flash to my TCM at the same time as a bunch of other stuff. Mine shifts very nicely.
I know looking at your sig it will take some work to get in dealer ready trim. The tranny is the most critical and expensive part on the Dodge that I'm worried about. Only reason I got extended warranty.

Your flash I see is AR and mine is AG I wonder if that could be causing the downshifts..

 

[dad2bike]

Those are the flash levels for the ECM, not the TCM. I dunno what the TCM level is. I just know there was a TCM update that came out at the same time as my AR flash level did.

Oh... I wonder if there is a way someone could send that like H&S can with the ECM flashes

I would check your belt but I have heard lots of CTDs chirp on shut down. The motor is coming to a stop really quickly and with the momentum all the accessories, the belt can chirp. With the 4wd thing, have you tried rocking the wheel or even backing up if it gets stuck? When I first started using my 4wd, I noticed every once in a while, it would stay in 4wd when it said it was in 2wd but after rocking the wheel while driving, it took that little bit of tension off the TC and would unlock. Doesnt do it anymore though.

4WD comes out when i put it in reverse and it doesnt do it all the time just kind of random.. If it is being shut off so quickly if i were to let it idle for a minute or so would this help? also my turbo makes like a rubbing noise when i turn it off and i can really hear it coming out of the exhaust. thanks

the only help i have is about your chirpping noise. it is normal, whether its the turbo or just the release of compression i dont know, but it is ok

Idling wont help because it is the difference of tension that helps it come out of 4wd. Imagine it locked and while you may not notice it, the front and rear drive shafts may have a little tension on it due to turning, terrain or whatever the case may be. When you go to unlock it, that difference in tension can potentially keep it locked until the drive shafts rotate or attempt to rotate at a different speed. Usually when I unlock 4wd, I make sure that I am not into the throttle so I know the front and rear wheels are all rolling together the same and no additional strain is being up on the TC durring unlock. Mine hasnt gotten stuck in 4wd in a really long time and when it did, all I did was rock the wheel back and forth going a couple miles an hour and that slight difference unlocked it right away. Never does it anymore though.

The "rub" noise you hear, does is sound like a creeking or deepish squeal on shutdown. This noise you may be hearing is the turbo actuating. From what I have heard is on the 6.7s on shut down, the slides of the turbo move back and forth to kind of clear any soot. Its another update to help keep the turbo from acting up. Its normal and no big deal at all.
