In an automatic transmission, transmission fluid helps cool and lubricate its internal parts. Your vehicle’s transmission is responsible for transferring power from the engine to the wheels of your car. An automatic transmission shifts the vehicle into different gears depending on the speed that you are driving. The transmission has an oil pan that contains the transmission fluid and fluid filter. The fluid provides the power/force required to shift into different gears.
A safe interval to replace your transmission fluid is about once every 40,000 miles. If you notice any fluid underneath the car, you should get it inspected as soon as you can. Changing your transmission fluid regularly will greatly extend the life of your vehicle’s transmission.
Here are some of the common symptoms that tell you you need to get your transmission fluid replaced:
– Vehicle has a hard time running
– Vehicle stalls when on a steep incline
– Check engine light is illuminated
– Transmission making abnormal noises
An automatic transmission fluid service consists of replacing the transmission pan gasket, filter, and transmission fluid. Some vehicles do not have a serviceable transmission filter, and some transmissions are designed to be sealed for the life of the vehicle, meaning that they do not require any service or maintenance. Your vehicle’s owner’s manual should tell you whether you have a sealed transmission system or not.
Automatic transmission fluid service is done by draining the transmission fluid, installing a new pan gasket and filter (if applicable), refilling the proper type and quantity of oil & fluid, checking for leaks, and a test drive to ensure everything is working properly.
Transmission fluid service is an important part of regular maintenance, and will increase the service life of your transmission. 90% of automatic transmission failures are caused by overheating, which can often be avoided by keeping your transmission fluid fresh and performing optimally.
