Under normal driving conditions, heat and oxidation causes deterioration of the fluid, while abrasives and contaminants in your transmission increase. Over time, your transmission becomes more vulnerable to costly breakdown, and loses its peak operating performance qualities. Under extraordinary driving conditions, the deterioration accelerates. Some of these conditions can include:

  • Towing or operating under heavy loads
  • Hot climates
  • Stop-and-go city driving
  • Winter or hard driving
  • AWD or 4WD usage
  • Hills or mountainous terrain

What about my car’s warranty? 

Changing the fluid in your transmission at regular intervals is recommended by your vehicle manufacturer, and is required as part of your extended warranty obligations (see your owner’s manual for warranty details). It’s essential to perform regular maintenance to your vehicle that meets or exceeds the manufacturer’s recommendations.

Recommended service intervals: please check your owner’s manual
