Replacing your transmission fluid can be affordable and generally is cheaper if you do it yourself. For manual transmission, you can replace your transmission fluid for around $150 (and you don’t need to replace a filter).
The average cost for replacing automatic transmission fluid is between $80 and $250, with the average at about $100. If you want to get your fluid flushed and your filter replaced however, average costs will be between $230 and $475.
When you do replace your fluid, make sure to get the filter replaced and the pan cleaned every time you change the fluid to prolong the lifespan of your transmission and avoid serious damage to the car.
In this article, we will explain what transmission fluid is, the types, how to check and change your fluid, what to choose and when to change your transmission fluid.
What Is A Transmission Fluid?
A transmission fluid is a special lubricant that is manufactured to help protect the cars transmission gears and clutch packs to allow for a smooth shift and to also keep heat from destroying the fluid.
Transmission fluid is a lubricant used in internal combustion engine-powered vehicles like passenger cars.
This fluid helps lubrication reduce friction between moving parts and lessen the amount of heat being produced. Transmission fluid also transfers heat away from the transmission and other internal components of the engine to help keep it cool.
You should check your transmission fluid level on a regular basis and replace it when it’s low or starts breaking down.
Automatic Transmission Fluid Change Cost
An average independent mechanic will charge you somewhere from $100 to $250 for this service. The low end of this range is for the fluid change only, while the high side is because you likely have a transmission filter that should also be replaced. Dealerships will typically charge a higher price as well.
Parts, if you do it yourself, will run you on average about $50-$100, but can vary depending on how many quarts of fluid and the type of fluid. You will need a new transmission filter, and possibly a new pan gasket, but those estimates may vary higher or lower as well.
To know what you will pay specifically, you will need to get a quote, typically over the phone from a mechanic or a dealership.
In most cases, providing a mechanic or dealership with the year, make, and model of your vehicle will be enough for a quote or estimate.
Depending on the shop you take your vehicle to, there will be tax and a disposal fee added to the total amount.
When to change the fluid
Most car manufacturers recommend that your vehicle gets a new automatic transmission fluid every 100,000 miles, and some as much as 150,000 miles.
However, the problem most mechanics and garages are going to tell you that you really only have 30,000 to 60,000 miles because that is just way too long to wait. We you may suggest a flush instead, but if it were me, I would pass on that as well.
Anyway, just like the typical oil change interval, it is really up to your driving style to know when, during a given interval, to change your automatic transmission fluid.
It is still highly recommended to have your fluid changed as over time automatic transmission fluid will break down just like any other automotive fluid, and the longer you wait from your suggested interval the worse it is for your vehicle.
This is especially apparent if you are usually driving under stressful situations on your transmission, as in a stop-and-go situation or “spirited” driving.
But, don’t worry, because if you regularly take your car to an oil-change shop or dealership, then they will check your automatic transmission fluid and will let you know the correct time to either get your automatic transmission fluid changed or flushed.
Sometimes, some signs will let you know when to change your automatic transmission fluid.
For example, if you have issues shifting gears into your automatic transmission, that would suggest your transmission fluid is dirty.
You may also feel your vehicle surge forward or backward due to the dirty transmission fluid not flowing properly.
Anything abnormal like these symptoms should send you to get your fluid changed immediately.
Choosing The Right Transmission Fluid
Choosing the correct transmission fluid is necessary for your vehicle to be able to operate properly. Here are a few things to help you make the proper decision:
Know Your Vehicle
There are different types of vehicles that will require different types of transmission fluid and it is important to make sure you are using the proper types for your vehicle. Refer to your owner’s manual for suggestions regarding what type of fluid will work best for your car.
Understand Your Needs
When determining what type of transmission fluid to choose, the primary determinant is the type of transmission. Manual transmissions require a thicker type of transmission fluid, while automatic transmission typically requires a thinner fluid. Choose the fluid that meets your needs.
Consider The Climate
Some transmission fluids work better in colder climates while some work better in warmer climates. Be sure to consider the climate where you’re located when choosing your transmission fluid.
Check The Quality
Not all transmission fluids are created equal. Make sure you check the quality of the fluids that you are purchasing in order to ensure you’re getting a decent product.
Look For Recommendations
If you’re still not sure which way to choose, look for recommendations from a trusted mechanic or an automotive supply store. They can assist you in finding the proper fluid for your vehicle and needs.
How To Change and Check the Transmission Fluid
It is a simple maintenance item to check and change the transmission fluid, which can assist you in keeping your car operating smoothly and even safely. Here’s a guideline on how you do this:
- Retrieve the owner’s manual for the type of transmission fluid your car uses, and make sure that you have the proper amount.
- Optionally lift the car. Go underneath it and look for the transmission fluid pan.
- Unscrew the bolts, pull the pan off.
- Then drain the fluid into a container. Check the fluid’s color and odor. If it is dark and smells burnt, it needs to be changed.
- Clean the pan and reinstall it.
- Refill the transmission with the proper kind of fluid.
- Now start the car, check the dipstick for proper amount. If low, add more fluid, re-insert dipstick, and close the hood.
DIY vs. Professional Services
Pros and Cons of DIY Transmission Fluid Change
Choosing a DIY change of transmission fluid can appear to be a good option to some car owners because they can save money and enjoy the feeling of hands-on maintenance.
The benefit is obvious: you save money by doing it yourself, and you spend no money on labour by someone else. But as with anything, DIY has its complications. You need to get the levels just right, install everything correctly, and make sure you are following a number of steps, etc.
However, if you don’t have the right mechanical skills or tools, there is a risk you can cause more damage than good (especially on modern vehicles that have complex transmissions). In addition, you must consider any servicing warranties, as a DIY change may void car warranties that specify professional service.
It is also important to weigh the potential savings, against accuracy, and warranty compliance for those who wish to DIY their own change of transmission fluid.
Benefits of Professional Service
When it comes to professional services there is no shortage of benefits. With professional auto shops you can employ a skilled technician who is trained or knowledgeable and is consistently reviewing the principles and procedures surrounding the work of a transmission fluid change.
A professional auto shop has access to specialized equipment that many individuals do not have, improving the precision and thoroughness of the procedure.
Then there is the job guarantee. Many professional auto shops will offer a warranty for the work they have completed, providing an element of peace of mind to car owners. If something goes wrong after the fact, the warranties provide coverage for repairs, adjustments, etc., after a service, and at no additional payment to the car owner.
Yes, the cost of a professional change of transmission fluid is more than a DIY, but when you are receiving knowledge, tools, and services warranty it may just be worth it based on how long you own the vehicle and how much you value your vehicle’s transmission system!
Extending the Life of Transmission Fluid
If you want to reduce the frequency of changing your transmission fluid and extend the life of the fluid, consider the following:
- Regular Checking: Check daily, weekly, or reasonably regularly the fluid levels and conditions to prevent it from deteriorating before your next change.
- Service Intervals: If the manufacturer recommends a service interval for changing the fluid, do so on time (for example, going over service intervals can result in the fluid breaking down and its initial capacity as a lubricant/heat sink).
- Temperature Regulation: Keep the transmission system at a constant temperature as much as possible. Either ensure nothing impairs the cooler, add a transmission cooler, or don’t load up your vehicle with heavy loads and drive it to it limits in extreme conditions.
- Fluid Quality Selection: Use the finest quality transmission fluid recommended for that vehicle by the manufacturer.
- Prompt Action to a Problem: If you notice issues with the transmission system, act quickly. Issues left too long can worsen, creating costly repairs, and your delay does not improve the value of your car.
By doing these simple things, car owners can create a practical service regime that extends the life of the transmission fluid but also protects the transmission system of the vehicle.
