Why Gl4 Manual Transmission Fluid is Necessary

As a car enthusiast, I have come to understand the importance of maintaining proper lubrication in a vehicle’s transmission system. And when it comes to manual transmissions, using the right type of fluid is crucial for its smooth operation and longevity. This is where Gl4 Manual Transmission Fluid comes into play.

First and foremost, Gl4 Manual Transmission Fluid is specifically designed for manual transmissions, which operate differently than automatic transmissions. Manual transmissions rely on a clutch system to engage and disengage the gears, while automatic transmissions use a torque converter. Therefore, the viscosity and additives in Gl4 fluid are tailored to meet the unique needs of manual transmissions.

Moreover, Gl4 Manual Transmission Fluid contains additives that protect against wear and tear, corrosion, and oxidation. These additives create a protective film that prevents metal-to-metal contact between moving parts, reducing friction and heat build-up. This not only ensures smooth shifting but also prolongs the life of your transmission.

Furthermore, using the wrong type of transmission fluid or neglecting regular fluid changes can lead to serious damage and costly repairs. Many manual transmission manufacturers recommend using Gl4 fluid specifically because it meets their performance requirements. So by using Gl4 Manual Transmission Fluid, you are not only
