What is Transmission Fluid?

Transmission fluid plays a multifaceted role in your Mazda 5’s performance and long-term health. Essentially, it’s the liquid that lubricates, cools, and cleans the internal components of your vehicle’s transmission.

Think of it as the ‘oxygen’ that enables the ‘lungs’ of your vehicle—its transmission—to function optimally. Let’s delve into the roles it plays:


The transmission is made up of an array of gears, clutches, and bearings that need constant lubrication to function correctly.

The transmission fluid ensures that these components slide smoothly against each other, reducing friction and preventing wear and tear. Inadequate lubrication could result in the metal parts grinding against each other, leading to irreversible damage.

Cooling Agent

Transmissions generate a significant amount of heat due to the friction between the moving parts. The transmission fluid serves as a cooling agent, helping to disperse this heat and maintain a stable operating temperature.

An overheated transmission can lead to malfunction and even total failure, making the cooling property of the fluid invaluable.


As time passes, tiny metal shavings and other contaminants may accumulate in the transmission. Quality transmission fluid contains detergents that help clean these particles, keeping the transmission components in optimal condition.

Hydraulic Function

In automatic transmissions, the fluid also serves a hydraulic function. It helps facilitate gear shifts by activating the appropriate clutches and bands.

Without the correct fluid level or type, you may experience erratic or sloppy gear shifts, affecting your driving experience and potentially causing accidents.

For your Mazda 5, choosing the correct type of transmission fluid and maintaining the right capacity is crucial for ensuring smooth gear shifts, preventing overheating, and prolonging the lifespan of your transmission system.

Ignoring this important aspect of vehicle maintenance could lead to expensive repairs or even total transmission failure. So, as a responsible Mazda 5 owner, it’s crucial to understand the ins and outs of your vehicle’s transmission fluid needs.
