What transmission does the LaCrosse 2.0T use?
2 Answers
The LaCrosse 2.0T uses a 6-speed manual-automatic transmission. Introduction to this transmission: A manual-automatic transmission is a gear-shifting device that combines the functions of manual and automatic transmissions. This transmission combines the advantages of both automatic and manual transmissions, minimizing power loss in the shifting system. Introduction to the LaCrosse: The LaCrosse is a new mid-to-high-end sedan launched by Shanghai GM on February 22, 2006. Positioned between the Regal and Royaum, its main competitors include the Teana and Accord. Shanghai GM introduced the LaCrosse to replace the Regal and secure an important position in the domestic mid-to-high-end car market.
While delving into the Buick LaCrosse 2.0T, I discovered it's equipped with a 9-speed automatic transmission, officially named the Hydra-Matic 9T50. Developed by General Motors, this transmission features nine forward gears and was designed to enhance fuel efficiency and shift smoothness. In real-world driving, it delivers quick acceleration response from a standstill, with nearly imperceptible gear changes, especially during highway cruising where it can maintain lower RPMs for improved fuel economy. Compared to the older 6-speed transmission, it boasts optimized electronic controls that reduce jerking sensations, though occasional delayed starts may occur in extremely cold weather. For maintenance, it's recommended to inspect the transmission fluid every 60,000 kilometers and replace it promptly to prevent internal wear. Overall, this 9AT performs reliably for daily use, with fuel consumption kept within reasonable limits.
