Why Transmission Flushes Are Important

Why Transmission Flushes Are Critical to Your Vehicle’s Health

When it comes to car maintenance, oil changes and tire rotations often steal the spotlight. But if you want your vehicle’s transmission to last and perform at its best, a transmission flush should be on your radar. Transmission flushes should be performed as preventative maintenance before any issues occur such as slipping or hard shifting. 

What Is a Transmission Flush?

A transmission flush is the process of cleaning out old, degraded transmission fluid and replacing it with fresh fluid. This isn’t just a top-off it’s a complete exchange that removes built-up contaminants and grime from your transmission system.

Why It Matters

Your transmission fluid plays a vital role in lubricating, cooling, and cleaning the moving parts inside your transmission. Over time, this fluid breaks down, becoming less effective and potentially harmful. Neglecting it can lead to:

  • Slipping gears
  • Rough shifting
  • Increased wear and tear
  • Complete transmission failure

Transmission Flush vs. Fluid Change

Not all services are equal. A basic transmission fluid change only drains part of the fluid. A flush removes almost all the old fluid, along with harmful debris that accumulates over time. Think of it like replacing stagnant water in a fish tank it’s about restoring balance and performance.

How Often Should You Get One?

This depends on your vehicle type and driving habits, but most manufacturers recommend a flush every 30,000 to 60,000 miles. If you frequently tow, drive in stop-and-go traffic, or operate in extreme heat (hello, Arizona summers), you might need it sooner.

Signs You Might Be Overdue

  • Fluid that looks dark or smells burnt
