If you didnt see it, heres the article on GMs NEW transmission where they admit they fixed the problems we have been complaining about and they have been ignoring.

Here’s the gist:
In a line buried deep within a previous announcement uncovered by GM Authority, Chevrolet states that the 8-speed Hydra-Matic in the 2019 Silverado features “enhancements designed to improve shift quality, as well as a new centrifugal pendulum absorber torque converter that reduces vibrations to improve smoothness.”

Criticisms
In prior-generation, K2 platform Silverado and Sierra, the GM 8-speed was often criticized for its jerky and unexpected shifting behavior that ultimately worsened the satisfaction of driving and/or riding in the pickup. Whether the improvements made to the 8-speed gearbox in the all-new T1 platform 2019 Sierra and Silverado will address these issues is unknown.

Availability
The revised 8-speed transmission is assigned RPO code MQE and is available in conjunction with the turbo-charged 2.7L I-4 L3B engine as well as the naturally-aspirated 5.3L V-8 L84 EcoTec3 engine.

By comparison, the 8-speed automatic in the last-generation Silverado and Sierra is assigned RPO code M5U.
