The common issues with the XT6 transmission are: low-frequency exhaust pipe noise, jerking, and gear dragging. The function of the transmission is to change the transmission ratio to expand the range of torque and speed variations of the drive wheels, adapting to frequently changing driving conditions and allowing the engine to operate under favorable working conditions. Taking the 2021 XT6 as an example, its body dimensions are: length 5056mm, width 1964mm, height 1777mm, wheelbase 2863mm, and fuel tank capacity 73L. The 2021 XT6 features a MacPherson strut front suspension and a five-link independent rear suspension. It is equipped with a 2.0L turbocharged engine, delivering a maximum horsepower of 237PS, maximum power of 174kW, and maximum torque of 350Nm, paired with a 9-speed automatic transmission.

I've been driving the XT6 for over half a year, and there are some minor issues with the transmission that frequently occur, especially in urban congested areas. When shifting at low speeds, the jerking sensation is particularly noticeable, making the car shake uncomfortably. According to discussions in the car owners' group, this is related to the design of Cadillac's universal transmission, possibly caused by software tuning issues leading to delayed shifting. Last time I went to the dealership for a check-up, the technician said this is a common issue with the XT6. The solutions are system upgrades or oil changes, but if ignored, it could accelerate part wear over time, or even worse, require transmission repairs, which would be costly. It's recommended that owners perform regular maintenance and avoid sudden acceleration to alleviate the problem.

Reasons for the Rattling Noise When a Car Goes Uphill

Detailed explanation about the rattling noise when a car goes uphill is as follows: The sound comes from the car's valves. There are valves in the engine's valve train, and during normal operation, they produce a rattling sound, but it is usually faint. If the valve sound becomes louder, it may be due to insufficient engine oil, causing the valves to lack lubrication, which increases the noise. Another possible reason is excessive valve clearance. The sound from valves lacking lubrication due to insufficient engine oil. Many car engines use direct fuel injection technology, which requires higher injection pressure. Engines with direct injection technology have a high-pressure fuel pump in the engine compartment, and this pump produces a rattling sound during operation, which is normal. Additionally, many cars will have a rattling sound when the engine hood is opened.

What is the equivalent car displacement for a 500cc motorcycle?

The displacement unit for motorcycles is milliliters, while for cars it is liters. Since 1 liter equals 1000 milliliters, a 500cc motorcycle is equivalent to a 0.5-liter car displacement. Motorcycle displacements can be categorized into five types: Ultra-lightweight. Lightweight. Small-to-medium displacement. Large displacement. Liter-class large displacement. Motorcycle displacements can be divided into five categories: Ultra-lightweight: Below 100cc, including 50-90cc displacements such as 50, 70, 80, and 90. Lightweight: 100-150cc, including displacements like 100, 110, 125, and 150. Small-to-medium displacement: 200-400cc, including displacements such as 200, 250, 300, and 400.

Is the Original Factory Paint of a Car Important?

Original factory paint is very important as it primarily protects the car body from corrosion. The original paint refers to the paint used when the car leaves the factory. During the car body painting process, different stages use different coatings, forming distinct layers. On the car body steel plate, there are four paint layers: the electrophoretic layer, the primer layer, the base coat layer, and the clear coat layer. A significant difference is that the original factory paint is a high-temperature paint, baked at least at 130 degrees Celsius, resulting in stronger adhesion of the coating. In contrast, the repair paint used for touch-ups is typically baked at around 80 degrees Celsius, with much weaker coating adhesion. This is because the original primer is applied in the factory's paint shop by immersing the entire car body in a paint bath and attaching it through cathodic electrophoretic deposition—a process that cannot be replicated after leaving the factory. The primer used in touch-ups is usually a post-phosphatization coating, incomparable to the original factory primer, and the application process is vastly different.
