NHTSA Complaint #11524650 — 2016 CHEVROLET TAHOE

While traveling a major highway (70 mph) over the holiday weekend, I experienced a loss of engine power. The RPM's went up to 5 while I decreased speed. I had gone from 75 MPH down to 35 while trying to maintain speed up a hill. I pulled over to the break down lane to let traffic pass and when it was safe, I tried to engage the vehicle to speed. It would slip gears and continue to lose momentum. The check engine light came on so I pulled it into a rest area and called for a tow. When the tow truck arrived and I needed to turn the car on to put it in neutral, the check engine light had turned off. After having it towed and a mechanic diagnose the issue, it was found that the transmission was blown. The transmission fluid is black and contains metal slivers. I had just had my transmission fluid checked during a tune-up. The fluid was changed at 70,000 miles. I have 113,000 miles on it now. The only warning I got just prior was a vibration similar to needing a front end alignment. There were no other warnings. Like I said, the fluid was checked a month prior to this incident.
