Mercedes-Benz CLS Transmission Fluid Change Intervals

Changing the transmission fluid at regular intervals is vital for maintaining the longevity and performance of a vehicle’s transmission. For Mercedes-Benz, given its standing as a luxury vehicle brand, adhering to these intervals is paramount to ensure the vehicle operates at its peak performance.

While specific transmission fluid change intervals can depend on the model year, driving conditions, and the specific model, a general guideline for many Mercedes-Benz vehicles, including the CLS-Class, is as follows:

  1. First Change: Typically, the first transmission fluid change is recommended at around 40,000 miles (approximately 64,000 kilometers). This initial change helps remove any contaminants or debris that may have settled in during the break-in period of the vehicle.
  2. Subsequent Changes: After the first change, it’s advisable to replace the transmission fluid approximately every 60,000 to 70,000 miles (approximately 96,000 to 112,000 kilometers).

However, there are a few important points to consider:

  • Driving Conditions: Vehicles that often drive in harsh conditions such as frequent stop-and-go traffic, mountainous regions, or those that regularly tow heavy loads might need more frequent transmission fluid changes.
  • Vehicle Model and Year: Mercedes-Benz, like all automakers, periodically updates its service recommendations based on the latest engineering data and real-world performance metrics. Thus, newer models may have different service intervals than older models.
  • Transmission Type: Different transmission systems can have varied fluid requirements and change intervals. Always refer to the specific transmission type and the associated recommendations.
  • Owner’s Manual: The owner’s manual will always provide the most accurate service intervals for a specific vehicle. This should always be the primary reference point for any maintenance-related questions.

For an owner of a Mercedes-Benz CLS-Class, or any other vehicle for that matter, regularly consulting with a certified technician or dealership can also help ensure the vehicle is receiving the appropriate care based on its age, mileage, and driving conditions.
