What is the importance of Flushing your Automatic Transmission?

Helping car owners understand the different kinds of preventative maintenance that will extend the life of any vehicle is important to us at Triangle Transmissions. Hense we are committed to explaining how processes like a transmission flush can help you get more life out of your car. Drivers tend to overlook essential flushes because they are due as rarely as every 50000 Km, depending on the make and model of the vehicle. Still, knowing about them is important because when fluids reach the end of their lifespan, they lose the ability to protect your vehicle. Transmission fluid is no exception.


Transmission fluid is a type of oil with specific viscosity achieved by the right combination of chemicals and additives. This balance is important because it serves as the lubricant and coolant for the gears in the transmission, ensuring that they operate smoothly during changes and prevents them from overheating and seizing. When transmission fluid breaks down enough that its viscosity changes,it no longer maintains the balance that those fine gears need to function properly. Over time, the excess heat and wear caused by spent transmission fluid could contribute to other problems, and may eventually lead to a complete transmission failure.


A transmission flush not only replaces your expended transmission fluid,it also cleans the transmission as it changes the fluid over. It also manages to replace more of the fluid than a simple draining and replacement procedure does, so you get more improved performance after a full flush than you do after a simple replacement. By cleaning your transmission with a flush as you replace the fluid, you gain the following:


  • Reduce or eliminate debris or contaminants that appear in the transmission over time as parts wear
  • Obtain a more complete replacement of the fluids
  • Lower wear and tear on other engine system components, promoting overall vehicle life
