Automatic transmission fluid is a type of oil that is used to lubricate and cool the moving parts of your car’s transmission. The fluid also helps to clean the transmission, keeping it free of dirt and debris. Transmission fluid needs to be changed on a regular basis in order to keep your car’s transmission in good working order. Here is what you need to know about automatic transmission fluid.
Automatic Transmission Fluid History
Though the earliest cars were manual, early inventors quickly realized the potential for an automated system. The first patent for an automatic transmission was filed in 1921, and the first production car with an automatic transmission was introduced in 1940. However, it wasn’t until the 1950s that automatic transmissions became widely available. The main reason for this delay was the high cost of producing the necessary components. In the early days of automatic transmission production, each car required its own specific fluid, which made it difficult and expensive to produce. In the 1970s, a universal fluid was developed, making it possible for all cars to use the same fluid.
Today, automatic transmission fluid is an essential part of every car with an automatic transmission (in other words, the vast majority of vehicles on the road). It keeps your car’s transmission cool and lubricated and helps to prevent wear and tear. Eventually, however, automatic transmission fluid can break down, causing your transmission to operate less efficiently. As a result, it’s important to regularly check your transmission fluid level and condition and to replace it according to your manufacturer’s recommendation. By doing so, you can help keep your car running smoothly. You can usually have this done as part of routine service at your favored auto shop.
Maintain Your Automatic Transmission Fluid
People often are unsure of how often they should have the fluid changed or what type of fluid to use. First, check your car’s owner’s manual to see what the manufacturer recommends for the frequency of changes. In general, most carmakers suggest changing the fluid every 30,000 miles or so. However, if you do a lot of stop-and-go driving or drive in extreme conditions (hot or cold weather), you may need to have the fluid changed more frequently. As stated, you can also have your mechanic check your transmission fluid level during routine maintenance visits to see if it needs to be changed.
The automatic transmission fluid is one of the most important fluids in your car. When it comes time for maintenance, make sure you use the correct type of fluid for your car. By consulting your owner’s manual or asking a qualified mechanic about changing your automatic transmission fluid, you can ensure safety on the road.
