Don't Let Your Transmission Down: The Importance of Regular Fluid Changes

Your car's transmission is the unsung hero, silently orchestrating gear changes to deliver smooth, efficient power. But like any hardworking component, it relies on proper care to function at its best. One crucial aspect of transmission health is regular fluid changes. Here at Certified Performance, we want to shed light on what happens to your transmission with old, dirty fluid, and why maintaining a fresh flow is vital.

The Breakdown on Dirty Fluid

Transmission fluid performs several critical tasks: lubrication, cooling, and hydraulic pressure. Fresh fluid is slick and efficient, minimizing friction between moving parts. However, over time, the fluid degrades:

  • Lubricity Breakdown: Worn-out fluid loses its lubricating properties, leading to increased friction and metal-on-metal contact. This translates to grinding noises, jerky gear changes, and a decrease in overall transmission performance.

  • Cooling Compromise: As the fluid ages, it loses its ability to absorb and transfer heat. This can lead to overheating, further accelerating fluid breakdown and potentially causing internal damage.

  • Hydraulic Pressure Woes: Dirty fluid can clog passageways within the transmission, hindering the flow needed for proper hydraulic pressure. This pressure is vital for gear engagement, and insufficient pressure can lead to slipping gears and a loss of power.

The Importance of Regular Changes

By neglecting regular transmission fluid changes, you're setting your transmission up for a fall. Here's why staying on top of this maintenance is crucial:

  • Preventative Maintenance: Fresh fluid ensures proper lubrication, cooling, and hydraulic pressure, preventing the wear and tear that leads to costly repairs down the road.

  • Smoother Operation: Clean fluid translates to smoother gear changes and a more enjoyable driving experience.

  • Extended Transmission Life: Regular changes help your transmission live a long and healthy life, saving you from the hassle and expense of premature transmission failure.

How Often Should You Change Your Transmission Fluid?

Your vehicle's owner's manual will have specific recommendations for transmission fluid change intervals. These intervals can vary depending on factors like your driving habits and the type of transmission. Regardless of the mileage recommendation, be mindful of any warning signs that might indicate the need for a change, such as:

  • Grinding or clunking noises during gear changes

  • Hesitation or slipping between gears

  • Burning smell coming from the transmission
