   I am experiencing ongoing issues with the 6L80E transmission that have significantly affected the performance and reliability of my vehicle. The transmission shifts harshly between gears, hesitates when accelerating, and occasionally slips before engaging. There is also a noticeable shudder during acceleration and inconsistent shifting, especially at lower speeds.

   Within the first week of buying my 2014 GMC 1500 SIERRA, the transmission fluid was black in griddy. I have had it flushed, then filter changed and new fluid put in within 2 week time frame. A week later had to put a new transmission in it. It barely would drive. So a purchase at 2,999 then to a transmission 4,800 and new control arm with ball joint with new axels. They were busted. Another 2,000. Its sicking. Advice

    I was driving around a lake with my family. We were fishing. I had no warning at all and my transmission started to sputter and jerk extremely bad and my brakes did not work at the same time. I had to use my parking break to stop my family and I from going into the lake at 40mph. I looked up on many websites and forums and saw multiple people with the same issue. I am afraid that this will happen to a young driver and it be very tragic. Please do a recall. My truck is still…
