Average Cost Of A Transmission Flush (2025)

As of October 2025, the price of changing the transmission fluid in the US depends on a number of things, such as the type of service, the specs of the vehicle, and the cost of labor in the area. Here’s a full look at it:

Average Prices:

Changing the transmission fluid means taking out some of the old fluid and putting in new fluid. The average price is between $150 and $175.

Transmission Fluid Flush: This is a more thorough treatment that replaces all of the old fluid with new fluid. Prices usually fall between $125 and $250.

Extra Costs: Vehicles with sophisticated transmissions, including dual-clutch or CVT systems, may need special lubricants that cost more. Luxury or performance cars usually cost more to fix since they take more time to work on. Always check to see if the price includes both parts and labor.

Things that Affect Prices:

Type of Car: Manual transmissions usually cost less to service than automatic ones.
Service Provider: Independent shops may charge less than dealerships.
Differences by Region: Labor rates might vary by location, which can change the total cost.

Suggestions:

Look at your owner’s manual: Follow the manufacturer’s instructions for how often to service the car.
Get a lot of quotes: Check costs from several service providers to make sure they are competitive.
Be careful with services you don’t need: Some suppliers could suggest extra services that aren’t really needed.

To keep your car running well, last longer, and use less gas, you need to do regular maintenance, such changing the transmission fluid on time. If you don’t change the fluid, you could have trouble shifting, the gearbox could overheat, and it could eventually break down, which could cost thousands of dollars to fix. Keeping up with service intervals and staying educated will help you keep your expenditures down.

When Should I Change My Transmission Fluid?

How often you need to change the transmission fluid depends on a number of things, such as the type of transmission, the weather, and what the car maker says.

Automatic Transmission: Every 30,000 to 60,000 miles if you drive normally.
If you drive in bad weather (such towing, stop-and-go traffic, or very hot or cold weather), you should do it every 15,000 to 30,000 miles.

Most manufacturers say to change the manual transmission every 30,000 to 60,000 miles. Some older or high-performance manuals may need to be changed more often.

Every 30,000 to 50,000 miles (depending on the brand), a continuously variable transmission (CVT) needs to be changed. CVTs usually need certain types of fluids, so always use the one that is suggested.

Sealed gearboxes: Some newer cars have “lifetime” or sealed gearboxes, which the makers say don’t need to have their fluids changed. But a lot of mechanics say that to keep the performance up, you need change the fluid every 60,000 to 100,000 miles.

Things That Mean You Need a Change Sooner?

  • Problems with changing gears or gears “slipping’ when you change them.
  • Jerky or slower acceleration.
  • A Warning light indicating the transmission is running hot.
  • Low or dark fluid levels or a charred smell.

Look at your owner’s manual to see how often you should do this for your car. If you’re not sure, you might check the transmission fluid every 30,000 miles to see if it needs to be changed.
