What brand is the Regal transmission?

The Regal transmission is from the Buick brand. Buick is an automobile brand under General Motors, founded in 1900 in Detroit, Michigan, USA. The Buick logo features three differently colored shields arranged diagonally within a circle, representing the three models in Buick's 1960 lineup: Electra, Lesabre, and Invicta. Buick vehicles are known for their high horsepower, individuality, practicality, and maturity. Buick's model lineup includes: Excelle, Regal, LaCrosse, GL8, as well as models like the Rendezvous, Enclave, and Encore.

I've been driving a Buick Regal for several years, equipped with GM's 6-speed automatic transmission, and the gear shifts feel quite smooth. The Regal's transmissions are mostly produced in-house by GM, like the models coded 6T40 or 6T45, and the fuel consumption is well controlled during long-distance driving. There are no major issues in daily driving, but I've heard that some older models may experience jerking, so it's necessary to check the transmission fluid regularly. I change the fluid during every maintenance to avoid increased wear and tear, and I also recommend avoiding lugging the engine to extend its lifespan. The transmission performs steadily even on mountain roads. When chatting with friends about cars, we all feel that this brand is reliable, with many service points, unlike some imported cars where parts are hard to find.

Having worked at the service station for many years, I've commonly seen the Buick Regal equipped with the GM Hydra-Matic transmission, models like the 8L45 or 6L50, which feature a compact and efficient structural design. The operation is generally smooth without noticeable jerking, but it's important to note that electrical faults can cause shifting issues. Regular replacement of transmission fluid and filters can prevent abnormal noises, typically requiring inspection every 50,000 to 60,000 kilometers. In some cases I've handled, insufficient oil pressure led to slipping, which can be resolved with simple adjustments. Avoid reckless towing to prevent internal gear damage, and opting for genuine fluid for maintenance is both cost-effective and reliable.

From an automotive enthusiast's perspective, the Regal exclusively uses GM's in-house transmissions, such as the newer 8-speed automatic 8L90 model, which improves transmission efficiency, reduces fuel consumption, and delivers a smoother feel on highways. Compared to transmissions from other brands like Aisin or ZF, GM's technology is relatively low-profile but offers strong durability. Based on forum research, owner feedback indicates that occasional jerking and oil leaks are common minor issues, which can be optimized through software updates. The shift logic is continuously refined, making driving both enjoyable and well-suited for urban conditions. It's advisable to check the maintenance manual when purchasing to avoid unexpected issues.
