One of the most important elements of transmission maintenance is knowing when to change the system's fluid. This vital element lubricates the transmission and keeps it from overheating. By preventing excess heat and friction, the parts are less likely to experience wear and tear that lead to expensive repairs. Over time, however, high heat will cause the fluid to break down, causing it to perform less efficiently and potentially leave deposits on the transmission that hinder performance. Knowing when to replace this fluid will help you save money and enjoy a smoother ride.

When to Change the Transmission Fluid

For both automatic and manual transmission vehicles, most manufacturers recommend performing a transmission flush between 30,000 and 60,000 miles, though some automatic models can go as long as 100,000 miles before the fluid needs to be replaced. Unless you possess the knowledge and cleaning equipment to drain the old fluid from beneath the car before refilling the reservoir, it's best to take the vehicle into a professional shop.

While a transmission flush isn't done nearly as frequently as an oil change, the wide range in when you might need to change your transmission fluid means you should always consult the owner’s manual for your specific make and model. There’s nothing wrong with changing your transmission fluid more frequently, but going too long without a fluid flush can cause significant transmission maintenance issues.

When to Replace It More Often

While the guidelines in your owner’s manual are a good start, certain driving habits could require more frequent service. For example, if you regularly tow heavy loads or drive in stop-and-go city traffic that requires frequent gear shifts, you may need to replace the fluid more frequently.

These driving conditions create excess heat and friction, which will break down the fluid faster. Have a mechanic check the quality of your transmission fluid during other routine services to determine if you need a flush sooner rather than later.
