If you are not all that familiar with truck maintenance or care, you may not know a lot about this type of transmission repair.

How Often Does a Truck Need a Transmission Flush?

The frequency in which a transmission flush is needed varies based on a few factors. If you have a manual transmission, or a stick shift, it is recommended that you have the transmission flushed every 30,000 to 60,000 miles. If you have an automatic transmission, you will want to flush the transmission when your truck is showing signs of needing it done or based on what the manufacturer recommends. Always read your manufacturer's manual. It will tell you when the manufacturer recommends that you have a transmission flush done on your truck.

What Are the Signs That a Transmission Flush is Needed?

If your truck is in need of a transmission flush, it will give you many signs. Unfortunately, many of these signs are the same signs that your transmission will give if the transmission is failing. In many cases, flushing the transmission should be done to determine if your fluid is bad or if the transmission is in need of more extensive repairs or even replacement. Some of the signs that your truck and transmission will give you when a flush is needed include:

  • Grinding noises when the truck is shifting gears.
  • Hesitation or the feeling that your truck may stall when the truck is shifting gears, or slipping gears.
  • Explainable forward surging without stepping down on the accelerator pedal.
  • Difficultly shifting into gear when you have a manual transmission.
  • Feeling stuck or like your truck isn't moving after the truck has shifted gears.
  • The fluid has turned from red to a dark brown or black.
  • The sweet smelling fluid has a burnt scent to it.

What Happens if You Do Not Flush a Truck's Transmission?

As you drive your truck, the transmission fluid will flow across your transmission. The transmission can become dirty thanks to air. Dirt and dust can accumulate in the fluid and make the fluid thicker and sludge-like. When this occurs, your transmission may not be able to shift as smoothly and effortless as it did before. If you do not flush the transmission, the fluid will continue to become thicker. The shifting problems with your truck may become more pronounced, and eventually, your transmission may slip gears. You may need a new transmission or extensive and costly repairs if you do not flush the fluid when it needs to be done.

Flushing the fluid in your truck's transmission is important to overall health and longevity of your transmission. Learning more about this process will help you to better understand it and its importance. Visit websites like to learn more.
