Protect Your Transmission with Routine Fluid Exchange

Your vehicle’s transmission is one of the most important systems under the hood—and keeping it running smoothly starts with a regular transmission fluid exchange. At Oilex Grease Monkey®, our expert technicians perform fast, professional transmission services that help extend the life of your transmission while preventing costly repairs down the road.
Whether you drive a vehicle with an automatic transmission, manual transmission, or transaxle, we’re here to help with manufacturer-recommended transmission maintenance services.

What Is a Transmission Fluid Exchange?

Transmission fluid keeps your transmission components cool, clean, and lubricated. Over time, this fluid breaks down and collects dirt and debris, reducing its effectiveness. A transmission fluid exchange removes old, degraded fluid and replaces it with fresh fluid, restoring optimal performance and protecting your transmission from wear and overheating.

When Do You Need a Transmission Fluid Exchange?

Check your vehicle’s owner’s manual for recommended transmission service intervals—typically between 30,000 and 150,000 miles, depending on your vehicle make and model.

You may need a transmission fluid exchange sooner if you:

  • Tow heavy loads frequently
  • Drive in extreme temperatures or rough conditions
  • Spend a lot of time in stop-and-go traffic

What’s the Difference Between Transmission Fluid and Differential Fluid?

While transmission fluid supports gear shifts and system cooling, differential fluid lubricates the gears that transmit power from your engine to the wheels. Both are critical and often serviced together—especially in vehicles with a transaxle system.
