4wheel drive switches...stays in Neutral?

You may want to have the battery checked out to make sure it is up to par. You could be having a low voltage situation to the tccm when first starting it up causing it to do weird things.

I would like to revive this thread. Ive been experiencing the same problem. My TC tends to go from 4HI to The RED NEUTRAL Light on it's own. I would like to resolve this myself before taking it to the dealer. From the info I have gathered these could be some of the fixes but would like to hear from others who have resolved this

1- Replace TCCM Actuator?
2- Replace relay fuse?
3- Replace Encoder motor?
4- Go through all TC drives 25 times?

I can't find the old thread on this but I remember something about going from 4Hi into 4 Lo and 4 Hi lock several times to see if it clears things up.

Jim, I believe that would be similar to what Ive read by going through 4HI and 4LO 25 times. I don't see how that would work but I will give it a try. The funny thing is when the TC goes into Neutral, the truck seems to drive smoother however my gas mileage only averages 8.9 at best!!

i am having the same issue.
i thought maybe since i have not change my transfer case fluid (52K miles) it may be a warning to change it?
if you guys find a fix please post it.

Cesarjajr, does your light stay in Neutral or does it go back and forth to 4HI like mine? Has your gas mileage changed?

it stays red in netural, i have to hit the 4 hi and then it will stay on 4 hi.
it happens on and off. i shift to drive and sometimes it's red in neutral.
some times im already driving when i see it in red neutral and didnt see when it changed.
i have seen no dip in miles + or -.
