Transmission Fluid: An Overview

Transmission fluid is a crucial component that ensures the seamless operation of a vehicle’s transmission system. Here are its primary functions within the Mercedes-Benz GLC-Class SUV:

  1. Lubrication:
    • The fluid provides necessary lubrication to the moving parts within the transmission, reducing friction, preventing wear, and ensuring smooth operation.
  2. Cooling:
    • Transmissions generate heat during operation. The fluid helps dissipate this heat, maintaining an optimal temperature for the transmission components.
  3. Hydraulic Power Transmission:
    • In automatic transmissions, the fluid acts as a hydraulic medium, facilitating the operation of the transmission’s hydraulic components, and enabling gear shifts.
  4. Cleaning and Protection:
    • The fluid helps keep the transmission clean by suspending and carrying away contaminants, and it also provides a protective coating to prevent corrosion and wear.
  5. Sealing:
    • Transmission fluid assists in maintaining seals and gaskets within the transmission, ensuring a tight seal and preventing leaks.

Types of Transmission Fluid

There are several types of transmission fluid, each formulated to meet the specific needs of different transmission types and vehicle models. For the Mercedes-Benz GLC-Class SUV, the recommended type is usually specified by Mercedes-Benz. Here are common types of transmission fluids:
