Transmission services are one of the most vital aspects of auto maintenance, but many drivers don’t know when to change their vehicle’s transmission fluid. According to Quality Transmission Service of Anchorage, AK, this cooling lubricant is the lifeblood of your automatic transmission system. Here, their team of ASE-certified technicians offers insight into how you can replenish it like a pro.

You might have heard the rule of thumb that transmission fluid should be changed every 100,000 to 150,000 miles, but discrepancies between drivers make this range unreliable. After all, every driver has unique habits and travels different distances each year. In some cases, fluid condition could be in a poor state after waiting that long. Fluid checks are one of the most effective ways to determine when it's time for a change.

For the average driver, transmission fluid must be replaced every 30,000 to 60,000 miles. This averages out to a change every two to four years, a schedule that allows for a steadier stream of fresh, contaminant-free fluid. On the other hand, those who drive in more extreme conditions—especially anyone who tows, plows, or hauls heavy loads on a regular basis—may want to consider a transmission fluid change every 15,000 miles. 

If you're not sure about the state of your supply, you can always check it yourself to be safe. Healthy transmission fluid has a distinct red color that gradually darkens over time. If your fluid is excessively dark, or if it gives off a smoky smell, prevent expensive auto repairs by taking your vehicle into Quality Transmission Service immediately. Their skilled professionals will get to the bottom of the issue and have you back on the road as soon as possible.
