Fluid Exchange Modesto

What is a fluid exchange and why do you need to get one done your vehicle?

The Fluid is the reason your transmission and other, under the hood, parts stay cool and lubricated. The job of the transmission is to transfer power from the engine to the wheels of the car. If you have an automatic vehicle the transmission will shift the car into different gear depending on the speed that you are driving. The one difference in a Manual vehicle is that you’re the one shifting the gears. In both cases transmission fluid is necessary to keep your car running smoothly and clean.

If your automatic doesn’t have enough fluid, or it is contaminated, the transmission will start to slip and will eventually fail. If this happens to a Manual car the transmission will make a grinding noise the internal parts will wear out a lot faster and then it will fail. So if you hear the grinding noise while shifting gears make sure to call us at Walkers Automotive.

​Some things to Keep in mind:

An automatic transmission fluid service will replace the pan gasket, filter, and transmission fluid. Some vehicles do not have a serviceable transmission filter and some transmissions are designed to be “sealed for life,” meaning that they do not require any service or maintenance. Check your owner’s manual for information on whether you have a sealed system or not.

Unlike an automatic transmission, a manual transmission does not contain a filter, which means that as components wear, the transmission fluid picks up particles of metal and is unable to filter them. This is why it is very important to perform a transmission fluid service as per manufacturer recommendations.

​How a Fluid Flush is done

  1. Drain the transmission fluid
  2. (Automatic only) Install new pan gasket and filter (if replaceable)
  3. Add the proper type and quantity of oil/fluid for your transmission
  4. Check for leaks
  5. Test drive the vehicle

Our recommendation:

A conservative rule of thumb is that a car should get a transmission fluid service every 40,000 miles. If you notice any fluid underneath the car, get it inspected as soon as you can. Changing your transmission’s fluid regularly will greatly extend the service life of your vehicle’s transmission.

What are the common symptoms indicating you need to replace the transmission fluid?

  • Vehicle has a hard time running
  • Vehicle stalls when going up or down a steep incline
  • Check Engine Light is on
  • Transmission makes noise

How Important is a Fluid Exchange Service?

Transmission fluid services are an important part of regular maintenance and will increase the service life of your transmission. According to the Automatic Transmission Rebuilders Association, 90% of automatic transmission failures are caused by overheating and can be often blamed on transmission fluid that should have been replaced.

Top 10 frequently asked questions about Fluid Exchange:


1. What is auto fluid exchange?

Auto fluid exchange is a maintenance procedure where old, contaminated fluids in a vehicle are replaced with fresh fluids. This includes transmission fluid, engine oil, coolant, brake fluid, power steering fluid, and differential fluid.


2. Why is fluid exchange important?

Over time, automotive fluids degrade and accumulate contaminants. Regular fluid exchange helps maintain optimal performance, prevents damage to components, and extends the life of the vehicle.


3. How often should transmission fluid be changed?

Transmission fluid should typically be changed every 30,000 to 60,000 miles. However, check your vehicle’s owner’s manual for specific recommendations.


4. What are the signs that my vehicle needs a fluid exchange?

Signs include unusual noises, rough shifting (for transmission fluid), overheating (for coolant), spongy brakes (for brake fluid), and difficulty steering (for power steering fluid). Regular checks can prevent these issues.


5. Can I do a fluid exchange myself?

While some fluid exchanges, like engine oil changes, can be done by DIY enthusiasts, others, like transmission fluid exchange, often require specialized equipment and should be done by professionals.


6. Is flushing different from fluid exchange?

Yes, a fluid flush completely removes old fluid and any debris using a machine, whereas a fluid exchange typically involves draining the old fluid and refilling with new fluid. Flushes are more thorough but also more expensive.


7. What happens if I don’t change my fluids regularly?

Neglecting fluid changes can lead to poor vehicle performance, decreased fuel efficiency, and potentially severe damage to the engine, transmission, and other systems, leading to costly repairs.


8. How do I know which type of fluid my vehicle needs?

Refer to your vehicle’s owner’s manual, which specifies the type and grade of fluid required for each system. Using the correct fluids is crucial for proper operation and warranty compliance.


9. Can fluid exchange improve fuel efficiency?

Yes, maintaining clean fluids can reduce friction and improve the efficiency of your vehicle’s engine and transmission, potentially leading to better fuel economy.


10. Is synthetic fluid better than conventional fluid?

Synthetic fluids generally offer better performance, longer life, and improved protection compared to conventional fluids. However, they are also more expensive. Check your owner’s manual and consider your vehicle’s needs and usage.


Regular maintenance, including fluid exchange, is essential for keeping your vehicle running smoothly and efficiently. If in doubt, consult with a professional mechanic to ensure your vehicle receives the appropriate care.
