Transmission Fluid: Common Questions & Short Answers

Jimmy's Top Tech Auto • 2 May 2023

The proper level of clean transmission fluid plays an integral role in keeping your transmission in optimal condition. If your transmission fluid becomes polluted or gets too low, then serious problems could develop. This makes it important to be familiar with this vital automotive fluid. Here’s a look at some of the FAQ about transmission fluid.


What does transmission fluid do?

Transmission fluid serves several important functions. Among its important jobs are that it provides cooling and rust prevention. Also, it lubricates gears and clutch packs. And to create the fluid pressure necessary for successful gearbox operation, you need the right amount of clean transmission fluid.


What are common problems related to transmission fluid?

If your car suddenly pops out of gear while you’re driving, then there may be contaminants in your transmission fluid that are impeding the fluid’s flow, causing fluid pressure to drop to the extent that the car won’t reliably stay in gear. Also, you’ll want to watch out for signs of transmission fluid leaks, such as reddish-colored fluid on the ground below your vehicle or a worryingly low reading on your transmission dipstick.


How regularly should I check transmission fluid?

Even if you don’t suspect an issue with your transmission fluid, you should still check it each month. This way, it’s much more likely that you’ll notice early if your fluid gets too low or starts burning. Generally, it’s best to check transmission fluid with the engine still on.


Why is transmission fluid red?

Transmission fluid’s bright red color lets you know that the fluid is healthy. If the fluid turns darker, then you’ll want to have the mechanic take a look so the underlying issue can be identified and addressed before it gets worse.


How often should I get my transmission fluid exchanged?

Commonly, transmission fluid is supposed to be exchanged somewhere between 30,000 and 50,000 miles. However, it’s best to consult your owner’s manual to see precisely how often your vehicle needs this to be done.
