Urgent * Aisin & 4 wheel drive service unavailable

Ok group, I've got a serious problem. I've got a 14 3500 srw with the Aisin. I've had Ray's complete option product installed for a month, over one thousand miles.

While driving last night, I was about half way through a 30 mile trip. It was around 68 degrees and lightly raining, mildly accelerating getting close to 60 mph and the truck down shifts, check engine light comes on, and I got the 4 wheel drive service temporarily unavailable message on the dash.

While driving seemed the the truck was stuck in gear and the manual shift buttons would not work. Got home and put the truck in reverse and BAM. Into park went smooth, then into drive BAM. I thought I was going to drop everything under the truck. I used my mm3 and there weren't any DTCs. Let the truck sit over night and this morning the same alarm but I'm not going to drive it in fear of more damage. The engine is running fine.

Couple questions:

Has anyone experienced this?

Is there a way to check the TCM for codes?

Shocked no replies on this thread... Anyways I'll update, the truck was taken to a dealer yesterday. No word back yet. BTW, truck has 63K, DRD installed for about 1500 miles or 1 month.

Please bump this thread for comments.

Thank you,

Keep us posted.

I think majority here are running 68RFE trans which is why the lack or replies.

forgive an ignorant old man, What is a "Ray's"? Are you talking about Ray at DRD?

First I saw this. Can't offer any help until I Know.

Return the truck to stock
@Double R Diesel

Yes it is Ray's from DRD.

Luckily it was a broken wire.

The dealer found it.

They said that it was spliced back together and it's back to normally.

I honestly was thinking about wiring . . . . That's the only logical choice. I bet it was a broken ground

Thanks for update!

I just saw this but had the same problem with mine. Mine was a squirrel got up on top of the trans and chewed up some wires. The wires are hard to see too.
