Transmission Fluid Change Cost (Best Cost Estimate)

You will need to change your automatic transmission fluid (ATF) if you drive a car equipped with one and do this per the manufacturer’s change interval. In most cases, it will happen every 100,000 miles. The transmission fluid filter will also need changing.

Although changing your transmission fluid and filter is a relatively simple task, many car owners prefer to have a professional do this job. This is because it is more complicated than the simpler ones. We can help you if you want to do it yourself.

This guide will explain everything you need about transmission fluid. It includes what it is and how often you should change it. We also discuss what transmission fluid change costs.

We will also provide a step-by-step guide for how to change your transmission fluid at home.

Transmission Fluid Change Cost

Transmission fluid change costs range from $80 to $250 if your fluid is changed by a dealer, service center, or independent mechanic. The average cost is around $100 for both automatic and manual transmissions.

You can expect to pay around $80 for the parts, but this will vary depending on the fluid type and how many quarts you have. You will also need a new transmission filter and possibly a pan gasket.

 Transmission Fluid Change Cost
Range$80 to $250
Do it Yourself$50 to $90
Mechanic$90 to $150
Dealership$150 to $250

To find out the exact cost of your specific repairs, get a quote from your local dealership or mechanic; this can be done over the phone. The most important factor in any estimate or quote they give you is the vehicle’s make, year, and model.

The shop’s total cost will include taxes and disposal fees depending on where they are located.

What is Transmission Fluid?

Transmission fluid is a lubricant that lubricates all moving parts of your car’s transmission. It also serves as a coolant, viscous fluid, and helps transmit power from your engine in automatic transmissions.

Different types of transmission fluids can be used in a car, depending on which vehicle has them. Manual transmissions can use any oil, including regular motor oil and specialized gear oil. Automatic transmissions use automatic transmission fluid.

Your car will determine which type of fluid to use, so make sure you check the manufacturer’s recommendations.

What Is A Transmission Fluid Change?

A transmission fluid change occurs when the fluid in your transmission system is replaced. The fluid in a transmission system can become contaminated with time due to wear and tear on the components. This causes some debris to get into the fluid. These particles will settle in the oil and won’t be able to lubricate as well as fresh oil. This could affect your transmission’s lifespan negatively.

The fluid will begin to degrade in cars that have a manual transmission. An automatic transmission system’s components are subject to the same wear as a manual system. This can also cause fluid contamination. These factors can lead to the gradual degradation of transmission systems over time. Regular transmission fluid changes are therefore recommended.

Transmission fluids is similar to motor oil and must be periodically changed along with the filter to ensure your vehicle’s proper functioning. Every 30,000-60,000 miles, or every two years, a transmission fluid replacement should be performed. To find out the recommended maintenance interval, consult your car’s owner manual.

What Are The Signs You Need Transmission Fluid Change?

Some of the most frequent signs that tell that you should change your transmission fluids are:

  1. Incapacity to shift
  2. Gear slippage
  3. Shifts that are not regular
  4. Delayed gear shifts
  5. Transmission that has been overheated

Benefits Of A Transmission Fluid Change

Regularly changing the transmission fluid will keep it in top condition and prevent any severe damage. This can extend the life expectancy of transmission components and save you money in repairs.

It is expensive to repair or replace a transmission. Take precautions to make sure it remains in top condition.

You can identify potential problems ahead of time by checking your transmission fluid regularly. The dipstick should be checked once a month. If the fluid is still red, it is in good condition. It’s time to change it if it has a dark color or a strong smell. You should top up your levels if they are low.

It’s possible to change many fluids yourself, so why not the transmission? You can change your transmission fluid yourself, but that doesn’t necessarily mean it’s a good idea. The same thing goes for any DIY project; You may not feel too confident in your abilities, and the job could be a disaster.

A Transmission Fluid Change is something you will need to do on your own. Although this is not as thorough as a complete flush, it will do more than top up the old fluid.

Here are the tools you will need for a transmission fluid change.

  • New Transmission fluid
  • Floor jack + jack stands + wheels chocks
  • Screwdriver
  • Ratchet
  • Socket Set
  • Drain pan
  • Long neck funnel

Follow these steps to know how to do a transmission fluid change.

  1. Allow your engine to warm up, then check the levels with your fluid dipstick. You should see a red handle on the dipstick. You may not need to make any changes if the fluid levels are normal. It can be topped up if the levels are too low. It should be replaced if it is sludgy or off-colored.
  2. After turning off the engine, place the wheel chocks between the rear wheels. To raise and secure your front end, use the jacks and jack stands.
  3. Under the engine, locate the transmission pan. The plug can be pulled out depending on the make and type of the fluid. Others will require removing the entire pan, which will involve removing 6-8 bolts.
  4. Drain the fluid by placing your drain pan underneath the plug. You will need a drain tray larger than the transmission pan if there is no drain plug. Otherwise, it will be messy. This will likely get only half the fluid out. To do a full and thoroughly clean, you MUST get a professional flush.
  5. Check the drain pan for any metal shavings or other contaminants. The pan should be fitted with a magnet to collect any metal shavings from your engine’s normal wear and tear. However, large, irregular pieces are rare.
  6. After the fluid has been drained, check the filter and gaskets. Replace any worn or cracked parts.
  7. Replace the pan or plug. Do not tighten the bolts too much.
  8. Place the car on jack stands, and then replace the fluid with a funnel. As detailed in the manual, you will need several quarts. You also need to be sure it is the right type for your vehicle.
  9. Let the car run for a while before you check your fluid levels. If it is low, add more.
  10. You must properly dispose of any old fluid. Transmission fluid should not be thrown in the garbage or flushed down the drain. Most shops will accept it for a drop-off.

2. Use Synthetic Transmission Fluid, If Your Car Can Withstand It

Because they work better than other fluids, synthetic fluids are very popular. They also have a better performance, according to research. They are resistant to cold, heat, and shearing, as well as oxidation. Check with your mechanic to see if synthetic fluid is possible in your vehicle.

3. Have Your Transmission Serviced Every 30,000 Miles

You may need to service your transmission every 30,000 miles if you own an older car, or if you live in a big city and drive a lot. You are doing preventative maintenance and can avoid costly repairs later.

4. Check And Maintain Your Car’s Cooling System

Your car’s radiator is there to keep the heat in your vehicle in check because heat is not good for the transmission. You should take care to maintain your car’s cooling system.

You may need to check your coolant levels at least once every two years. You should inspect your vehicle for damage and leaks or have somebody inspect your vehicle’s coolant levels.
