What is a transmission fluid service?
In this service, your mechanic will drain the transmission fluid and replace it with the correct type and quantity for your car.
Automatic transmission cars have an oil pan containing the transmission fluid and filter, which provides the power and force required to shift into different gears. You’ll need to buy automatic transmission fluid (ATF) for this service.
Manual transmission cars have a case that contains the transmission fluid. The fluid is not directly involved in shifting gears, but it can still experience wear and tear, eventually leading to a transmission failure.
How do I know if my transmission fluid needs servicing?
Getting your transmission fluid serviced between 30,000 and 60,000 miles is generally recommended, but check your owner’s manual for manufacturer’s recommendations.
Here are some typical signs that your transmission fluid needs servicing:
Your car has a hard time running
Your car stalls when going down or up steep inclines
The check engine light is on
Your transmission is making noise
How often should you have a transmission fluid service?
If you drive a manual car, most manufacturers recommend servicing your transmission fluid every 30,000 to 60,000 miles. If you drive an automatic, you can extend that to between 60,000 to 100,000 miles. But whether you hit the recommended mileage or not, it doesn’t hurt to change your fluid early.
If following a regular car maintenance schedule, changing your transmission fluid should be included in one of your maintenance services. But if you notice signs of bad transmission fluid early, take your vehicle in to be serviced.
Can I replace the transmission fluid myself?
If you want to save money on car expenses
and service your transmission fluid yourself, it is possible—but it’s a messy job, and you’ll need a few tools and items to change it. If you don’t have the proper tools and are not interested in getting a little messy, it’s probably best to leave the job to a professional.
