When Should You Change Transmission Fluid?

Service intervals vary by manufacturer, but most vehicles should have fluid replaced every 30,000–60,000 miles, or sooner if towing, driving in heat, or frequent stop-and-go traffic. We’ll test and show you the condition of your current fluid so you can make an informed decision.

Transmission Fluid Exchange FAQs

How often should transmission fluid be changed?

Most vehicles fall in the 30,000–60,000 mile range, but it depends on the manufacturer and how you drive. Towing, heat, and stop-and-go traffic can shorten intervals.

What happens if I delay a transmission fluid service?

Old fluid can’t protect or cool the transmission the same way. That can lead to harsh shifting, slipping, overheating, and expensive internal wear.

Is a fluid exchange the same as a transmission flush?

Not always. We focus on a controlled exchange using manufacturer-approved fluid and we check condition first, so the service matches what your transmission actually needs.

How long does a transmission fluid exchange take?

Plan for about 60–90 minutes for most vehicles. Timing can vary depending on access, filter service, and what we find during inspection.

Is it safe to drive if my transmission is slipping or shifting hard?

It can get worse quickly. If you notice slipping, delayed engagement, or burning smells, it’s best to schedule an inspection before damage spreads.
