Here are the pros and cons of the ATSL transmission: 1. Pros: The 2.0 engine is equipped with an eight-speed transmission, which provides continuous power whether at the moment of starting or during acceleration in later driving. 2. Cons: The biggest drawback is the high fuel consumption, heavy steering wheel, low-speed jerking, and slow transmission response. Additional information: The Cadillac ATS-L is a mid-size sedan under SAIC General Motors. The exterior adopts the concept of diamond cutting, which is quite stylish. The 2.0T turbocharged engine has a maximum power of 279 horsepower and a maximum torque of 400 Nm, paired with an 8AT automatic transmission. The interior is sufficiently refined. The chassis features a front-engine rear-wheel-drive structure with independent suspension.

I've studied the ATS-L's transmission for a while, having driven both the 6-speed and 8-speed automatic versions. The advantages are its smooth shifting, especially with the 8-speed which responds quickly with downshifts during acceleration. The vehicle stability system works well with it, delivering particularly smart power distribution when cornering. The robust construction makes it durable – I've seen examples running over 100,000 km without major repairs. The downsides include occasional jerks at low speeds, especially during cold starts. Fuel consumption is somewhat high in city driving, and the shift logic isn't very intelligent in traffic jams. Maintenance parts are more expensive than Japanese cars in the long run, but the overall durability is truly impeccable.

I drove my friend's older ATS-L, and the 6AT transmission performed decently. The gear shifting felt solid, and power delivery during acceleration was quite smooth. It was comfortable for city commuting, and the shifting rhythm remained stable on the highway. Maintenance wasn't too troublesome, though a transmission fluid change cost nearly two thousand. The most annoying part was the occasional shuddering at around 1500 RPM during low-speed follow-up driving. It improved a lot after we went for a software update last year. Compared to modern dual-clutch transmissions, the shifting speed is indeed a bit slower, but the upside is it's less prone to overheating and stalling.

GM's transmission system is quite interesting. The steel belt drive design minimizes shift shock and delivers power directly and briskly. The torque converter is tuned for a sportier feel, downshifting much more aggressively than typical commuter cars. However, the programming can be a bit stubborn—it often hesitates for half a second before downshifting when you floor the throttle. The gear ratios of the new 8AT are well-arranged, keeping RPMs impressively low during highway cruising. The cooling system is conservatively designed, making it prone to overheating protection during spirited driving. Oil leaks due to aging sealing rings are a common issue, so it's recommended to inspect the oil pan every 50,000 kilometers.
