2017 Chevrolet Colorado transmission problems

Filed Nov 7, 2026 · Transmission · OH

I purchased a new 2017 Chevrolet Colorado on XXX. On about XXX the truck started shuddering or not shifting correctly. I took my truck to the local dealer [XXX] GM. There the diagnosed the problem to be the torque converter. According to what they told me GM instructed them to drain and replace the transmission fluid. GM knew the 8-speed transmission had a design defect in the torque converter. The torque converter clutch fails to engage smoothly, creating the shudder vibration. A fluid flush treats the symptom, not the cause. GM was permitted to put a band aid on a problem to get the vehicle through any warranty and make it not their responsible. The vehicle was returned to me, even after I complained to the dealer that this was not fixing the problem. And the truck continued to have a pause in the shifting. On about XXX the shuddering became much more apparent. I made an appointment with this same dealer that had done all of my service. On about XXX they did confirm the the problem was the torque converter. At this point the truck was no longer under the warranty, so GM had succeeded in putting the replacement of the faulty torque converter on me the consumer. As a consumer I feel I have been failed by a system we have in place to protect consumers from dishonest Corporate transactions. This process cost me $4000.00 out of pocket, and 11 days without the use of my truck. All of this transpired, because GM decided to not do what was right and fix what they knew was defective.
