3 Answers
The transmission model of the Cadillac CT6 is the 8L90, which is a 10-speed automatic manual transmission, combining ten gears with both manual and automatic shifting functions. The Cadillac CT6 is a compact SUV with body dimensions of: length 4600mm, width 1881mm, height 1627mm, a wheelbase of 2779mm, a fuel tank capacity of 60 liters, and a trunk capacity of 447 liters. The Cadillac CT6 is equipped with a 2.0T turbocharged engine, producing a maximum horsepower of 237 PS, a maximum power of 174 kW, and a maximum torque of 350 Nm, paired with a 9-speed automatic manual transmission.
I understand that the transmission models of the Cadillac CT6 vary across different model years. For example, the earlier models from 2017 to 2019 mostly used the 8L90 8-speed automatic transmission, which emphasizes quick response and fuel efficiency, making it suitable for various road conditions. Starting from 2020, it was upgraded to the 10L90 10-speed automatic transmission, where the additional gears provide smoother shifting, especially during high-speed cruising, reducing fuel consumption and optimizing overall driving performance. General Motors has improved reliability and adaptability through model updates. I recommend owners check their vehicle manual or VIN to confirm their specific model, as there may be slight variations depending on engine configurations like V6 or V8. Transmission maintenance is crucial—regular oil changes help prevent jerking issues. Overall, the choice of transmission models reflects technological iteration, enhancing long-term driving satisfaction.
As a long-time CT6 owner, I drove the 2018 model equipped with the 8-speed transmission (model 8L90), which offered quick overall response but had slight jerkiness at low speeds. Compared to the new 10-speed model (10L90), gear shifts are smoother, especially with noticeable fuel efficiency improvements in city driving. The transmission model significantly impacts driving experience—I noticed the 10-speed version delivers more consistent power output during highway cruising, with quieter engine noise. When buying, check the model year and configuration, as performance variants like the CT6-V may have special tuning. Don’t overlook transmission health—regularly inspect the oil filter and sensors to prevent minor issues from affecting safety. Ultimately, choosing the right model can greatly enhance comfort, a lesson I’ve learned firsthand through practical experience.
