As part of the Mercedes SUV lineup, the GL-Class offers a harmonious blend of spaciousness, off-road capability, and state-of-the-art features, making it a preferred choice for those seeking a blend of luxury and versatility.

Transmission fluid plays a pivotal role in the overall health and performance of a vehicle. It serves as the lifeblood of the transmission system, ensuring smooth gear shifts, reducing wear and tear, and preventing overheating.

For a powerhouse like the Mercedes-Benz GL-Class, maintaining the right transmission fluid quality and level is paramount. The fluid not only lubricates the moving parts within the transmission but also helps transfer power from the engine to the wheels.

Transmission Fluid Basics

Transmission fluid is more than just a lubricant; it’s a multifunctional component crucial for the optimal operation of a vehicle’s transmission system. Its primary roles include:

  1. Lubrication: It reduces friction between the moving parts of the transmission, preventing wear and tear. This ensures smooth gear shifts and prolongs the life of the transmission components.
  2. Cooling: The transmission generates heat during operation. The fluid helps dissipate this heat, preventing the transmission from overheating and ensuring it operates within the desired temperature range.
  3. Power Transmission: It acts as a hydraulic fluid, facilitating the function of the transmission’s hydraulic system. This system controls gear shifts by modulating fluid pressure.
  4. Protection: Modern transmission fluids contain additives that protect metal surfaces from corrosion, enhance fluid stability, and extend the fluid’s lifespan.

Varieties: The world of transmission fluids is diverse, with various types formulated to meet specific vehicle requirements. Some of the common types include:

  1. Dexron/Mercon: These are the most common types of transmission fluids used for older models and some modern automatic transmissions.
  2. Synthetic: Made from artificially produced compounds rather than crude oil, synthetic fluids offer better performance, longevity, and resistance to high temperatures.
  3. Type F: Specifically designed for Ford vehicles, it’s different from Dexron and Mercon in its frictional properties.
  4. CVT (Continuously Variable Transmission) Fluid: Designed for vehicles with CVT transmissions, it ensures smooth operation of the belt-driven system.
  5. ATF+4: Used primarily in Chrysler vehicles, it’s a synthetic fluid known for its longevity.
  6. MB 236.14/236.15: Specific to Mercedes-Benz vehicles, these fluids are formulated to meet the brand’s stringent requirements. The color and specification (like MB 236.14 or MB 236.15) can indicate the fluid’s properties and intended use.

When choosing a transmission fluid, it’s essential to refer to the vehicle’s owner’s manual or consult with the manufacturer to ensure the correct type is used. Using the wrong fluid can lead to decreased performance, premature wear, and potential transmission damage.
