AAA w/RV rider really works!

[Denis4x4]

Set out for a week of travel to Shooting Star in Escalante, North Rim of the Grand Canyon and a couple of days at Gouldings in Monument Valley. Everything was great. Left Torrey UT on the way to Escalante and 10 miles south of town, the transmission shifted into 4-low by itself and the hot transmission fluid light and traction sabelizer lights came on. Called On-star and they were little or no help. At that point, the gears were gone. AAA sent a rollback with a trailer hitch with the correct size ball and towed me to Wonderland RV park in Torrey. Chevy dealer in Richfield picked up the truck last night and will call me later today.

When the dealer picked up the 2012 Silverado 4x4 crewcab 2500 HD, there were 964 miles showing on the odometer! Before leaving Durango, I weighed the AS at the gravel pit and it was 6240 pounds, well within the GCVW of 16,000.

My wife has lost confidence in this truck and I'll probably take a beating and buy a new Ford...or sell everything and go back to building and driving hot rods!

That is bad luck. Sorry to hear those kinds of stories.

I'm glad that the AAA service was good for you.

Regarding the Chevy, you know this is an outlier. Chevrolet will of course want to repair it, most likely by swapping in another transmission and sending this one off to figure out what went wrong since it blew up so young. Keep DETAILED records of this. If you continue to have issues with the truck, look up "Magnuson Moss warranty" and get your money back. It's a bit early to eat that depreciation, but it's never too early to be prepared.

Is it the Duramax/Allison combo? Or the 6-liter gasser?

Wow! Not exactly how you planned to spend your vacation! Can the dealer give you a truck fitted out to tow so you can continue your trip?

At only 900+ miles, sounds like you got a lemon. We have three Ford P/Us, one since '75 that we bought new, and they are all real troopers: no mechanical problems. Our main TV is the '08 diesel that is sheer luxury in its towing capacity (our 34' Ltd, 7000 lbs with ease), reliability (no problems, ever [knock on wood!]), and comfort.

Well, I sure hope you can work something out to continue your trip, but if not, just camp in that RV park and enjoy the relaxation: lemonade out of a lemon! You have my deepest condolences, but of course, as Airstreamers, we are all just a cup of motor oil/transmission fluid or some small crucial part from a similar fate. Try to enjoy yourselves anyway.

Sounds more like the electronic switch malfunctioned and forced the gear change.

Dropping a transfer case into 4-lo at Hwy speeds will surely lunch a trans and transfer case. Have the dealer check all three.

Well that sucks! That haul up through the Dixie Forest is long uphill grade. Hope they don't try to point the finger on the break-in period. Is it supposed to be 1000 miles before towing?

Well, that sure sux the big one. What you are describing must be a control module malfunction. Did you feel any driving difference when the shift into 4 wheel low occurred? Please keep us posted.

Hi, I fully understand your frustration, but don't give up so fast. Let GMC fix it, that's why you have a warranty. Definitely a big inconvenience for you. Keep us updated on what GMC does for you.

UPDATE....service manager found a service bulletin about a connection between the CPU and the trans module. I insisted that they change the trans fluid and filter. While doing that, they discovered that there was a kink in the line to the cooler that apparently occurred at the factory! Should be ready to roll tomorrow.
