What transmission does the Cadillac XTS use?
3 Answers
Cadillac XTS uses a 6-speed automatic manual transmission, and the entire lineup is equipped with a 2.0-liter turbocharged engine. This engine has a maximum power of 198 kilowatts and a maximum torque of 269 Newton-meters. AT transmission generally refers to an automatic transmission, which is a transmission device that can automatically shift gears based on the vehicle's speed and engine RPM, as opposed to a manual transmission. The Cadillac XTS is a large luxury sedan, with body dimensions of 5103mm in length, 1852mm in width, and 1502mm in height, and a wheelbase of 2837mm.
I've been repairing cars for 15 years and have disassembled many XTS models. The early versions used GM's own 6AT transmission, model 6T70. All pre-2018 models came with this transmission - the shifts weren't particularly fast but it was durable and reliable. After the mid-cycle update, they upgraded to an improved 6T75 version which had much smarter shift logic, able to reach 6th gear at just 80 km/h, making it very fuel-efficient on highways. When paired with the 2.0T engine featuring cylinder deactivation technology, there might be occasional minor jerks between 2nd and 3rd gears in traffic, but this improves significantly after a transmission fluid change. Never skimp on transmission fluid for American cars - changing to OEM fluid every 60,000 km will basically prevent any issues.
Last year when I accompanied my uncle to pick up a used XTS, I did some research and found the transmission quite interesting. Although it's a 6AT, there are two versions: the 2013-2017 models use the Hydra-Matic 6T70, while post-2018 models are equipped with the 6T75. The newer transmission has more aggressive programming, allowing it to drop two gears instantly when you floor the accelerator. My uncle's 2015 model always gives a noticeable clunk when shifting from R to D during cold starts, but it behaves normally once warmed up. The mechanic said this is a common issue with the solenoid valves, and replacing them with upgraded valve bodies for 800 yuan can fix it.
