Chevrolet Colorado shuttering and loss of power during acceleration and deceleration despite transmission flush on Chevrolet Colorado

Some Chevrolet Colorado owners report experiencing shuddering and loss of power during acceleration and deceleration, even after having a transmission flush. These issues are often linked to transmission problems, particularly with the second generation's 8-speed transmission, which has received complaints of shuddering and jerkiness from 2017 to 2019. Additionally, many owners of the 2018 model report noticeable shuddering or vibrations at lower speeds or during acceleration. Some drivers have encountered random stabilitrak service messages, along with erratic speedometer and RPM gauge readings, accompanied by intermittent engine power loss. The transmission may also exhibit shuddering during light throttle acceleration between 30 and 70 mph, resembling the sensation of driving over rough pavement. Furthermore, torque converter issues can contribute to these symptoms, especially when towing or operating at higher torque speeds in lower gears. Given these persistent concerns, it is advisable for owners to seek a thorough inspection by a qualified mechanic to identify and resolve the underlying mechanical issues.
