The Importance of High Mileage Transmission Fluid

As a car owner with a high mileage vehicle, I have learned the importance of using high mileage transmission fluid. At first, I thought it was just another marketing tactic to make me spend more money on my car maintenance. However, after doing some research and experiencing the benefits firsthand, I can confidently say that high mileage transmission fluid is necessary for any vehicle with over 75,000 miles.

One of the main reasons why high mileage transmission fluid is necessary is because it contains extra additives and seal conditioners that help protect and prolong the life of the transmission. As a car ages, its seals and gaskets become worn out, causing leaks and reducing the effectiveness of the transmission fluid. High mileage transmission fluid has specialized seal conditioners that help to rejuvenate and expand these seals, preventing leaks and maintaining optimal performance.

Additionally, high mileage transmission fluid has better heat resistance properties compared to regular transmission fluid. With age, transmissions tend to generate more heat due to increased friction from worn-out parts. This excess heat can cause damage to the internal components of the transmission if not properly managed. High mileage transmission fluids are specifically designed to withstand higher temperatures, ensuring that your transmission runs smoothly without any overheating issues.
