NHTSA Complaint #11552518 — 2017 CHEVROLET TAHOE

I just experienced an issue with my transmission, I was driving home from work in cruise control and started up a bridge when my vehicle seemed to disengage the clutch and start rapidly slowing down (I was going up the incline of the bridge) and the motor redlined trying to maintain speed. I immediately switched it back into regular drive mode and noticed that the engine was not engaging with the transmission. I then placed the column shift into the manual setting and dropped down to 3rd gear, the tahoe gave a really abrupt and hard impact on the transmission and I got it to reangage to continue up the incline. This happened more than a dozen times in the remaining 15 miles to my home, both in and out of the manual setting. I did not attempt to go back to curise control. When I got home I turned the car off and checked the trans fluid level and saw nothing on the dipstick, I let it cool off and I have fluid past the "hot" mark and into the S curve of the stick. I was able to determine that my transmission was having a majority of its issues beyone 3rd gear. After doing some very quick research on Google it appears that I'm not the only one having transmission issues, primarily with 3rd and 4th gear of this year make and model. Is this something that is being investigated? My vehicle has 103k miles and is planned for a fluid change in the next couple of weeks (transmission, transfer case, and rear differential), per the O&M book that came with the vehicle. This just happened today and I have not had an opportunity to reach out to the dealership to question them about it. There were no warning indicators or error messages during the drive or during the time this occurred. All recall notices have been repaired on the tahoe to date, and I have kept up with the other fluid changes and other misc o&m recommendations. Please, any feedback would be very appreciated as this is my primary and safest vehicle to transport my kids.
