What is the brand of the 9AT transmission in the Regal GS?
2 Answers
The transmission brand in the Buick Regal is the 9-speed HYDRA-MATIC intelligent transmission. Transmission Introduction: The transmission mainly refers to the car's gearbox, which is divided into manual and automatic types. The manual transmission primarily consists of gears and shafts, achieving speed and torque variation through different gear combinations, requiring the driver to use shift control. The automatic transmission (AT) is composed of a torque converter, planetary gears, a hydraulic torque variation system, and a hydraulic control system, achieving speed and torque variation through hydraulic transmission and gear combinations. When the driver engages the drive gear and releases the brake, the vehicle will move slowly. Vehicle Introduction: The 9-speed Hydra-Matic intelligent transmission equipped in the Buick Regal utilizes over 60 General Motors patented technologies, including a newly designed selectable one-way clutch, torque converter, start-stop hydraulic accumulator, externally mounted TCM control module, and a coaxial design that gives it a compact size comparable to a 6AT. With a compact structure and efficient transmission, the 9 forward gears have a closely and reasonably distributed gear ratio, with an overall gear ratio range reaching a wide 7.6:1. Along with the setup of two overdrive gears, it can significantly reduce the engine speed during high-speed cruising, improving fuel efficiency.
I've always been passionate about studying automotive technology, especially the powertrain of the Regal GS. This car's 9AT transmission comes from GM's in-house developed Hydra-Matic series, specifically the 9T50 model. GM has put great effort into vehicle manufacturing - this transmission features advanced design with intelligent and efficient shift logic, delivering an incredibly smooth driving experience like gliding on clouds. It also optimizes fuel economy while pairing perfectly with the Regal GS's engine for quick and stable acceleration response. After multiple test drives, I can confirm it never jerks even in congested urban traffic, demonstrating high reliability. With decades of transmission expertise, GM is truly trustworthy. Some owners report lifespans exceeding 100,000 km, but I recommend regular maintenance to check fluid conditions.
