What transmission was used in the old Buick Regal?
2 Answers
The old Buick Regal used a 6AT transmission. The AT transmission can also be called a torque converter transmission. This type of transmission is connected to the engine through a torque converter. When the torque converter is working, it is filled with transmission fluid. During gear shifts, the transmission fluid inside the torque converter absorbs some of the impact, which can improve the vehicle's comfort and shift smoothness. The old Buick Regal is a mid-size car equipped with a 1.5T L4 engine and a 9-speed automatic manual transmission. The engine has a maximum power of 125kW, a maximum torque of 252Nm, and a maximum horsepower of 170PS.
I've been driving an older Buick Regal for years and know it basically uses GM's 4-speed automatic transmission, with the common model being the 4T65-E. This transmission has a simple design and proves quite reliable in operation, especially suitable for stop-and-go city driving. While its gear shifts aren't the quickest, it's sturdy and durable. Some fellow owners have reported slight shift jerks, particularly during cold starts, which can be alleviated by regular transmission fluid changes. For maintenance, I recommend checking the fluid condition every 50,000 km to prevent component wear caused by degraded fluid. Overall, although its fuel consumption is higher than newer cars, it's a worry-free choice among older vehicles - economical and with few issues.
