FAQ: Transmission Fluid

Keizer Transmission • 18 March 2023

For your vehicle to shift smoothly and safely, it’s important that it’s operating with the right amount of uncontaminated fluid. At Keizer Transmission, we provide top-quality transmission service in the greater Salem, OR area. For transmission maintenance, such as fluid exchanges, come and see us at our Salem transmission shop. Here are some of the frequently asked questions about transmission fluid.


What does transmission fluid do?

Transmission fluid provides cooling and rust prevention. Also, it does the crucial job of lubricating gears and clutch packs. And unpolluted transmission fluid is integral to creating the hydraulic pressure necessary for your transmission to operate properly and to prevent gear slippage.


What are signs of an issue with transmission fluid?

Gear slippage is one sign of trouble. If you’re calmly cruising along and your vehicle suddenly pops out of gear, then there could be contaminants in your transmission fluid that are impeding the fluid’s flow, causing pressure to drop to the extent that your vehicle doesn’t remain dependably in gear. Transmission fluid leaks are also a common problem. A sign of such a leak is that there’s red-to-pink colored fluid below your vehicle. 


Why is transmission fluid red?

The bright red color lets you know that the fluid is healthy. When fluid turns dark, a transmission expert should conduct an inspection to identify the underlying problem.


How often should transmission fluid be checked?

Your transmission fluid should be checked every month, even if you don’t suspect a problem with it. Generally, it’s best to check your transmission fluid with the engine still on. By checking your fluid regularly, you’re more likely to notice early on if it’s gotten too low or has started to burn.


How often should transmission fluid be exchanged?

Transmission fluid commonly needs to be exchanged at a point between 30,000 and 50,000 miles, but you’ll want to consult your owner’s manual to see your car’s particular mileage point for this service.
