While pulling my 11,000 5th wheel trailer today. Going up an slight mountain highway incline at about 50mph. The truck came to a screeching halt. The rear axle left about a 6-8 ft skid mark from all 4 rear tires. As soon as the truck stopped, I was able to get pulled off to the side of the road. Thought we hit something. A look at the tires, driveline and any leaks maybe from the transmission. Nothing ? 

Drove about 2 miles up the road at about the same speed it happened again. The truck dash shows no check engine lights, did not flash anything at all. Parked the truck on a flat area and checked again. Nothing. 

Let the truck set for 30 minutes and then turned it around and headed back down the hill being super cautious. Made it home with no other issues and even had a steep pull out of a canyon at 35 mph. 

This is Friday at 4:30pm. No dealership in sight. 

 

Truck has 58,000 wirh no other issues. Transmission has NOT had its first service.

Electronic E brake kicked on since it was the rears? Thought I've seen a post elsewhere on here about it happening to someone else while driving.

There is another post about this occurring, I'm sure I have read about it recently.

 

Though that doesn't help you, I believe it was a simply fix if I recall correctly.

This is for the 1500 Silverado, but it appears to be VERY similar to what you are experiencing.

      How to Tune 6L80 Silverado transmission

      By ballencd · Posted

      New to this forum.  Also looking to tune a 6L80 and trying to work out all the issues in my transmission swap.  I have a 6.2 diesel (1983) and have removed the TH-400 and about to put in a 6L80 with a TCM-2600 interface and don't have a clue what I doing after that.  Did you (Leatherneck/RAV3) get your slip resolved? I too hate to spend that kind of money on a tuner that hopefully I will not need too many times although from what steelerdude15 added about the HP Tuner being great for diagnostics would be a plus.  I am also from WNC but below you in Columbus.  Any helo would be greatly appreciated.

      Sounds like a smart reasonable person with common sense. Bill O’Riley never said he was just a journalist, by the way.

      It's like saying Bill O'Reilly is "just" a journalist.         Lauren Fix, widely known as "The Car Coach," is a prominent automotive journalist, television personality, and self-identified conservative. She is a frequent contributor to right-leaning networks and platforms, offering commentary that intersects the automotive industry, consumer economics, and conservative political perspectives. [1, 2, 3] Media and Commentary Network Contributions: Fix serves as the National Automotive Correspondent for Newsmax and is a frequent guest on Fox News and Fox Business. Video Platforms: She has contributed to PragerU, where she has hosted videos critiquing government mandates on vehicles. [1, 2, 3] Core Positions Anti-EV Mandates & Fuel Policies: Fix regularly critiques government subsidies and mandates for electric vehicles (EVs), framing them as impractical and burdensome to the average consumer. She advocates for consumer choice and supports traditional internal combustion engine vehicles. [1, 2, 3] Economic Analysis: Her commentary often emphasizes the impacts of fuel prices, inflation, and federal regulations on drivers. [1, 2, 3] Political Alignment: On her public channels, she actively supports deregulation, "drill baby drill" energy policies, and the removal of government restrictions on auto sales and manufacturing. [1, 2] For analysis from Lauren Fix on how consumer automotive choices can align with political leanings:

      AFM Disabler Question

      Wouldn't swapping out the original AFM/DFM parts for a complete Delete Kit be the best route to go if one could afford to go that route?

      It comes with directions but yes, generally, it's the same.  Also, get you the dipstick stuff to install dipstick so you have one.
