Replace the old spark plugs? Check.
Swap out the grimy air filter? Done.
Change the transmission fluid? What?
This is one of those tasks that must never be disregarded. Luckily, it’s an inexpensive process, and if you have a basic understanding of mechanics, you can perform it in your own house.
What does it cost to modify transmission fluid? It depends on where you take it. At a mechanics shop or dealer, the price will likely range between $80 to $250.
However, if you’re willing and capable to do it yourself, it should fall between $50-$100.
Thankfully, in this thorough guide, I will cover everything you need to know about transmission fluid, including what it is, how often it needs to be changed, and what you can expect to spend for the service.
Finally, I will provide a comprehensive step-by-step guide on changing your transmission fluid at home.

What Is Transmission Fluid, And How Often Does It Need To Be Changed?
Transmission fluid is akin to engine oil in that it provides lubrication for the transmission – but it also functions as a hydraulic liquid.
It helps maintain the transmission at a secure operating temp, facilitates gear shifts, and lubricates the moving components.
Most transmission fluids contain:
- Lubricants
- Corrosion inhibitors
- Detergents
- Dispersants
- Surfactants
- Anti-wear additives
- Viscosity improvers/modifiers
- Seal swell additives
- Anti-foam additives
- Anti-oxidation compounds
- Cold flow improvers
- High-temperature thickeners
- Gasket conditioners
- Petroleum dye
When you are talking about a part that costs between $1,500-$3,500 to replace, does it really make sense to skip changing the one thing that keeps it functioning? Especially when the list of beneficial ingredients is as extensive as the one above.
Most transmission fluids last between 30,000-60,000 miles, though some claim to persist as long as 150,000 miles. The idea is not to see how long yours can last.
It is to keep it as streamlined as feasible to protect the transmission.
What are the signs that you need new transmission fluid? A few of the most prevalent signs include:
- Gear slipping
- Inability to shift
- Irregular shifts
- Overheated transmission
- Delayed gear shifts
Now that you know how vital transmission fluid is and how often it needs to be changed. Let us now look at how much you might expect to spend on the service.
How Much Does Changing Transmission Fluid Cost?
The first element influencing the cost is where you have it done – at a dealer or mechanic/service center. The next factor is the brand and model of your vehicle. This determines the kind of transmission fluid you need and how much.
Most transmission fluids range from about $8-$20 per quart, and various cars take between 5-15 quarts ($40-$300).
When you change your transmission fluid, you should also replace the filter and periodically the pan gasket. Filters range between $15-$30, and pan gaskets between $75-$150.
Add these all together, and you get a total cost of between $130-$480, with the typical price ranging from $80 to $250.
If you have the service performed at a mechanics shop or service center, expect it to be towards the cheap end. Otherwise, be prepared to spend more at a dealer.
If you’re willing to get your hands dirty, you can always change your transmission fluid for between $50-$100.
Not certain how?
Great news, we will cover that below.
How To Change Your Transmission Fluid At Home
Step #1: Jack The Front Of The Car Up
Start by sliding a jack under the front of your car and positioning it so that it sits under the frame. Next, place a jack stand in place to ensure it’s stable.
Step #2: Drain The Transmission Fluid Into A Drain Pan
Locate the bottom of the transmission. Next to it should be the drain bolt, which you will loosen using a hexagonal end.
You may want to wear some protective gloves because, once it’s loose, it will start gushing out. Finish by removing the bolt by hand.
Step #3: Remove The Pan And Change The Filter
If your vehicle is equipped with a filter, you’ll have to replace it with a new one.
You will see several fasteners around the pan. Remove them to free it so you can replace the filter and return the pan to its original position.
Step #4: Tighten The Drain Bolt And Refill
Grab your hex head and secure the drain bolt back in position. Then, you will need to determine how much fluid to add back in.
You can do this by taking the drain pan (that is now full of dirty transmission fluid) and pouring it into empty quart bottles. The number you need is how much to add back in.
The ultimate step is to locate the transmission fluid cap and pour the new fluid in.

Why Take The Risk? Instead, Maintain Your Transmission Fluid
As we mentioned earlier, the expense to replace a transmission usually ranges from $1,500 to around $3,500.
Which would you rather spend your money on, a new transmission or an $80-$250 fluid change every 30,000-60,000 miles?
We would unquestionably choose the latter.
