The titled question might seem odd, but we want to talk about what color the transmission fluid should be in your Mazda. Automotive fluid color is often an indicator of the fluid’s health, and if your transmission fluid isn’t the right color, it will let us know here at Mazcare that we need to give your transmission a complete inspection. Before we talk about the specific colors of transmission fluid and what they mean, know that this isn’t something you can easily check yourself, as the transmission oil dipstick is located underneath your Mazda. It’s easier to let a professional check your transmission fluid.
Good Transmission Oil Is Red
If you do crawl underneath your Mazda to check your transmission oil, it should be red with bright red being even better. Red is the color of the transmission fluid when it’s first put into your Mazda, so it’s safe to say that fluid is still in good shape if it is this hue. The fluid is clean, viscous, and able to continue to lubricate your transmission’s parts when it’s red or bright red.
Okay Transmission Oil Is Light Brown
If the fluid appears more light brown than red, it’s still okay for the time being, but you should schedule an appointment to have the fluid changed soon. Light brown transmission oil is getting dirty, but it isn’t so dirty that it will damage the transmission just yet. It’s also still lubricating the transmission parts okay. As the transmission oil begins to age, it will change from red to brown.
Dirty Transmission Oil Is Dark Brown
If you’ve driven your Mazda for more than 50,000 miles without a transmission oil flush, it’s definitely time for one and the fluid will likely be dark brown. To be honest, 50,000 miles is the longest you should go. It’s better to have the transmission oil changed every 30,000 miles. Dark brown transmission oil is dirty and no longer viscous, especially if the oil is almost black or is black. It’s time for a fluid change.
Coolant Mixed With Transmission Oil Is Pink
We hope your Mazda’s transmission oil is never pink because if it is, you’ve got a coolant leak. Coolant leaking into the transmission and mixing with the oil can seriously damage the transmission. The fact that the coolant is leaking into the transmission is also a sign of serious engine damage. In this case, you’re looking at much more than a transmission flush to fix the problem.
