What Transmission Does the Buick Regal Use?

[StAbigail]

Both the Regal 1.5T and 2.0T models are equipped with a 9-speed HYDRA-MATIC automatic manual transmission from General Motors. This transmission is designed for front-wheel-drive transverse platform vehicles and utilizes a one-way clutch, making its size comparable to a 6-speed automatic manual transmission. Below is relevant information about transmissions: Transmission: A transmission is a device that changes speed ratios and the direction of motion. It is used in automobiles, tractors, ships, machine tools, and various machines to alter the torque, speed, and direction of motion transmitted from the driving shaft to the driven shaft under different working conditions. Gear-driven transmissions generally consist of a casing and several gear pairs. Transmissions are divided into manual and automatic types. Manual transmissions primarily consist of gears and shafts, achieving speed and torque changes through different gear combinations. Automatic transmissions (AT) are composed of a torque converter, planetary gears, a hydraulic torque control system, and a hydraulic control system. Speed and torque changes are achieved through hydraulic transmission and gear combinations. Transmission Maintenance: Regularly replace the transmission fluid. For manual transmission vehicles, replace the transmission fluid every 3 years or 60,000 kilometers. For automatic transmission vehicles, replace the transmission fluid every 4 years or 60,000 to 80,000 kilometers.
