Transmission Fluid: FAQ

SM Transmissions • 8 January 2023

The right amount of clean transmission fluid is essential to keeping your transmission in great condition. When transmission fluid reaches a dangerously low level or becomes contaminated, significant problems may follow. Here’s a look at some of the frequently asked questions about transmission fluid.


What does transmission fluid do?

Transmission fluid has a variety of important jobs. It provides cooling, fluid pressure, and rust prevention. It also lubricates gears and clutch packs. 


Why is transmission fluid red?

The bright red color makes it clear that the fluid is in healthy condition. If your transmission fluid has turned darker, then there’s reason to suspect that something is causing it to burn. When transmission fluid is burning, the mechanic should take a look ASAP before the issue worsens 


How often should I check my transmission fluid?

Transmission fluid should be checked every month. This way, there’s a better chance that you’ll find out if it’s too low or burning before catastrophic transmission trouble occurs. Generally, transmission fluid is best checked with the engine still running. 


What are symptoms of a problem related to transmission fluid?

If your transmission fluid is contaminated, then your vehicle might suddenly slip out of gear while you’re driving. This could happen because the contaminants impede the fluid’s flow, causing a reduction in fluid pressure to the point that the vehicle won’t stay reliably in gear. Transmission fluid leaks are another common problem. A sign of such a leak is that there’s red-to-pink colored fluid on the ground beneath your car. 


How often should I get a transmission fluid exchange?

Transmission fluid is typically supposed to be exchanged somewhere between 30,000 and 60,000 miles. Your owner’s manual should inform you of the precise mileage point that your car needs this to be done. During a transmission fluid exchange, old polluted fluid is drained and replaced with clean fluid.
