How Often Does Transmission Fluid Need to be Changed?

If you are new to driving, you are in a constant state of learning. in case you didn't know, just like all other fluids in your vehicle, your transmission fluid also needs to be changed once in a while. But how will you know it is time to change it?

When to change your transmission fluid

Keep track of when you last had your transmission fluid changed since it has an expiration date. Although you shouldn't change it as frequently as your engine oil, you need to remain vigilant and develop a routine of monitoring it on a regular basis.

The lifespan of transmission fluid can range from 30,000 to 100,000 miles, with synthesized fluid surviving the longest. However, an automatic transmission normally needs the fluid replaced more regularly than a manual transmission. You will have to replenish your transmission oil more frequently if you are operating your car in circumstances that exert additional strain on the transmission.

If you frequently rest your leg on the clutch pedal between gear shifts in a manual transmission, this can result in a continuous source of friction and overheating, which could reduce the longevity of your transmission.

Why you need to monitor your transmission fluid

If you don't keep an eye on your synthetic oil, you run the risk of losing fluid due to a leak or poor upkeep. Your transmission may overheat and eventually fail.

The recommended maintenance plan in your vehicle's owner's manual will help you keep track of your transmission fluid. You must also become familiar with some of the telltale indicators that indicate it's time to replace your transmission fluid.

Transmission Fluid Change Warning Signs

If your transmission fluid appears dark brown or darkened instead of the typical bright red of fresh fluid, you might want to get your transmission looked at. Additional indicators that your gearbox needs new fluid include:

• Shifting Challenges

• Slipping Gears
