Why Transmission Fluid Matters

You might be wondering why transmission fluid is so important. Well, let’s break it down for you. The transmission fluid serves multiple purposes in your vehicle’s transmission system. It acts as a lubricant, ensuring that all the moving parts inside the transmission are properly lubricated, reducing friction and heat buildup. Additionally, it helps to cool down the transmission, preventing it from overheating during operation.

Furthermore, the transmission fluid also plays a crucial role in transferring power from the engine to the wheels. It allows for smooth and seamless gear shifting, ensuring that your vehicle accelerates and decelerates without any hiccups. Without the right amount and type of transmission fluid, your transmission system can suffer from excessive wear and tear, leading to costly repairs down the line.

  2. Locate the transmission dipstick, usually labeled with a bright-colored handle.
  3. Remove the dipstick and wipe it clean with a lint-free cloth or paper towel.
  4. Reinsert the dipstick fully into the transmission and then remove it again.
  5. Check the fluid level indicated on the dipstick. It should be within the “Full” and “Low” marks.
  6. If the fluid level is low, carefully pour the recommended transmission fluid into the dipstick tube using a funnel.
  7. Recheck the fluid level and add more if necessary, but be cautious not to overfill.
