Transmission fluid is pretty amazing stuff. It lubricates your transmission’s gears to keep them cool and prevent them from wearing down prematurely, but it also acts as a hydraulic agent to help your transmission shift the gears. Without this fluid, you wouldn’t get very far. In fact, if you don’t change your transmission fluid when it needs it, you’ll unnecessarily damage your car, truck, or C/SUV. LP & Sons Auto Care can check your transmission fluid. Here’s what the colors say about its health.
Okay, But What Color Is It?
Red. Your transmission fluid’s color should be red. It should be a bright shade of red that is also translucent, i.e. you can see through it. Red and translucent transmission fluid is new transmission fluid that is capable of protecting the transmission quite well. Remember, the fluid is also a hydraulic fluid, so red and translucent transmission fluid also keeps the gear shifts smooth and efficient.
What About as the Fluid Ages?
The fluid will begin to lose its bright red hue as it gets older. Two things are happening here. First, the fluid is losing its viscosity, so it isn’t protecting the transmission as well as used to. Second, it’s oxidizing, which can change the actual color of the fluid. Transmission fluid will start to turn light brown the older it gets. This color means the fluid is still okay as long as it is also still translucent.
My Transmission Fluid Is Brown
Once the transmission fluid turns brown, it’s time to change it. In fact, you should have the transmission fluid flushed and refilled as soon as possible. The darker the fluid turns, and it can actually turn black, the more oxidation is occurring, and this oxidation not only damages the transmission fluid but also makes it impossible for the fluid to protect your transmission. You’ll have gear-shifting problems, too.
What About Pink Transmission Fluid?
Pink transmission fluid is a sign that your transmission is seriously damaged – unfortunately. Red transmission fluid turns pink when it’s being diluted, and as with any lubricant, dilution reduces its effectiveness. Pink fluid is a sign that your transmission oil and engine coolant are mixing, i.e. you’ve got a serious leak. As the diluted fluid runs through the transmission, it damages the parts and gears.
It’s a good idea to have your transmission fluid checked regularly and changed every 30,000 miles. LP & Sons Auto Care can do that for you. We are the best auto service shop in DeLand, FL, if you don’t mind us saying!
