The transmission is responsible for channeling power from the engine into the wheels, so you can shift gears and maintain your desired speed. To perform such a critical role, this part requires regular transmission fluid changes. Learn more about this essential maintenance task below to keep your transmission in good shape.

What Is the Purpose of Transmission Fluid?

A transmission is composed of hundreds of pieces working together to harness the engine’s power. These metal gears, filters, and bolts require the fluid’s lubrication to prevent overheating, grinding, and breakdowns. When transmission fluid runs low or becomes dirty, your vehicle will have issues with torque, pressure, and heat management. 

Why Are Transmission Fluid Changes Necessary?

As with oil, transmission fluid deteriorates over time. Through ongoing use, this lubricant can become dirty, filled with debris, or evaporate, causing power, gear change, and driving issues.

A professional will clean the transmission and restore fluid levels, allowing you to shift gears as needed without the risk of overheating. Maintaining clean fluid will also help with hydraulics, so you can drive through bumps, hills, and tougher terrain. 

How Often Should You Schedule Fluid Changes?

As a general rule of thumb, mechanics recommend transmission fluid changes every 30,000 to 60,000 miles. For drivers who commute over varied terrain with frequency, this service may be needed as frequently as every 15,000 miles or along with routine oil changes. 

What Signs Indicate You Need a Fluid Change?

Dirty transmission fluid or low levels of lubrication can cause grinding or odd noises when shifting gears. Other signs you need service include trouble shifting, a sudden surging movement, delayed movements, or slipping into the wrong gear.

To check on the status of this lubricant, look under your hood for the transmission dipstick. With your engine running and in the park position, pull out the dipstick. Ideally, the fluid should be pink or clear. Brown residue, a burning smell, or a lack of moisture indicate it’s time for a replacement.
