What transmission does the Buick Excelle use?
3 Answers
Buick Excelle uses a 5-speed manual transmission and a CVT continuously variable transmission. The manual transmission, abbreviated as MT, is characterized by stability, reliability, simple structure, long development time, and very mature technology. The CVT transmission belongs to a type of automatic transmission. Common automatic transmissions can be divided into: hydraulic automatic transmission, dual-clutch automatic transmission, electronically controlled mechanical automatic transmission, and mechanical continuously variable automatic transmission. The Buick Excelle is an entry-level family sedan launched by SAIC-GM Buick. The prototype car is a globally developed mid-size sedan by General Motors, with a length, width, and height of 4468mm, 1765mm, and 1469mm respectively, and a wheelbase of 2611mm.
My old Excelle has been running for almost ten years, always with a manual transmission, the five-speed kind. Shifting gears feels quite smooth, especially when following traffic in the city—the clutch isn’t hard to press. I heard the early automatic models came with a 4AT, later upgraded to a 6AT, but fuel consumption is still higher than the manual. The latest Excelle now uses a CVT transmission, which should offer good smoothness. If buying a used car, pay attention to the transmission type—automatics after 2013 are mostly 6-speed, while the older 4-speed ones are prone to jerking issues. No matter which type you choose, regular transmission fluid changes are crucial—don’t wait for problems to arise before thinking about maintenance.
Last month, I just helped a friend repair a Buick Excelle with an automatic transmission. The model was a 6T30 six-speed transmission, while the older versions commonly used the 4T45 four-speed. Manual transmissions are mostly designed with five gears, and clutch disc wear is a common issue during repairs. Automatic transmissions are particularly sensitive to high temperatures; poor heat dissipation can easily cause internal friction plates to burn out. Feedback from new car owners mentions that the new CVT transmissions have significantly improved smoothness, and the use of steel chains makes them more durable than traditional steel belts. During maintenance, it's recommended to check the fluid level—discoloration or cloudiness indicates a need for replacement. Transmission fluid should ideally be changed every 40,000 kilometers to extend its service life.
