How Much Does a Transmission Fluid Replacement Cost?

Here’s what you’ll likely pay for changing the transmission fluid

A. Range

The average cost of replacing old fluid depends on your vehicle’s transmission system — manual, automatic, or continuously variable transmission (CVT). Let’s look at the price range for each. 

1. Manual transmission fluid (MTF) replacement can cost $120 to $230. This includes:

2. Automatic transmission fluid (ATF) replacement ranges between $300 to $510 and covers: 

3. Continuously variable transmission fluid (CVT) replacement may cost around $340 to $370.

Note: If your mechanic notices discolored liquid or thick sludge, they’ll suggest a transmission flush instead of a fluid replacement. Depending on your vehicle’s size, this service will likely cost around $150 to $400.

B. Factors Affecting Cost 

Some other factors that influence your expenses include:

Is It Worth Replacing the Transmission Fluid?

Certainly! 

Transmission fluid lubricates and cools system parts, helping them last longer. In automatic systems, this fluid creates hydraulic pressure to shift gears smoothly. 

If the fluid level reduces, the transmission won’t work, and you’ll experience gear-shifting issues. Once it runs out completely, the transmission system parts will overheat and become damaged. 

Eventually, you’ll witness a complete transmission failure, requiring expensive repairs. To avoid extensive damage, replace the fluid when you notice the red flags. 

Signs You Need a Transmission Fluid Change

If your car is running on low or dirty transmission fluid, you’ll notice:

  1. A lit Check Engine Light
  2. A puddle of dark red fluid pooling under the car near the transmission area
  3. Burning smell from the transmission 
  4. Grinding or knocking noises
  5. Gear shifting issues
  6. Slipping gears
  7. Slow acceleration
  8. The car surges and lunges unexpectedly

How Long Does Transmission Fluid Last?

Your car’s transmission fluid lasts about 30,000 to 60,000 miles or 2 to 5 years

However, the fluid can deteriorate faster if you:

How to Choose the Right Transmission Fluid for Your Car

Here are some tips to help you with your purchase:

Is It Easy to Perform a Transmission Fluid Replacement

Not at all!

Replacing the fluid requires raising the vehicle and handling complex transmission system components underneath it. That’s why you should always let an auto repair mechanic perform the transmission fluid exchange. 

But if you’re still curious, here’s a general know-how:

  1. Drive the car for 5 to 10 minutes to warm up the fluid. 
  2. Switch off the engine and park the vehicle. 
  3. Raise the car using jack stands and find the transmission pan.
  4. Remove the drain plug or unscrew the pan’s bolts to collect the fluid in a container.
  5. Inspect the transmission filter (in case of automatic transmission) and replace it if it’s clogged.
  6. Detach and replace the transmission pan’s gasket.
  7. Reinstall the pan and tighten the new gasket’s bolts as per the manufacturer’s recommendation. 
  8. Refill the system with new fluid. 
  9. Start the engine to circulate the fluid and shift gears into drive, reverse, and park mode.
  10. Check the fluid level with the dipstick and refill if needed. 

Should You Get a Fluid Flush Instead of a Fluid Exchange?

It depends. 

A fluid flush is needed when your transmission fluid is discolored or filled with metal shavings. During the service, the mechanic will drain 100% of your old fluid from the system using a flushing machine. Once the system is clean, they’ll use the same machine to add fresh fluid.   

However, if the fluid is mildly contaminated or low in level, they’ll replace it. The replacement involves switching 70% of the liquid with fresh fluid and inspecting the filter.

Typically, your mechanic should decide whether you need a transmission fluid flush or replacement.
