Quick summary
- Transmission fluid plays a crucial role in the smooth functioning of a vehicle’s transmission system.
- Excessive heat can cause the transmission fluid to break down and oxidize, resulting in a purple color.
- If the fluid is at a normal level and is not contaminated, observe the fluid for any further changes.
Transmission fluid plays a crucial role in the smooth functioning of a vehicle’s transmission system. It lubricates moving parts, dissipates heat, and protects against wear and tear. Typically, transmission fluid is red or amber in color, but certain circumstances can lead to it turning purple.
Causes of Purple Transmission Fluid
The most common reason for purple transmission fluid is contamination. When coolant leaks into the transmission, it can mix with the fluid, causing it to turn a purplish hue. This is a serious issue that requires immediate attention, as it can damage the transmission.
Other causes of purple transmission fluid include:
- Overheating: Excessive heat can cause the transmission fluid to break down and oxidize, resulting in a purple color.
- Additives: Some aftermarket transmission fluids contain additives that can cause the fluid to turn purple over time.
- Reaction with metals: Certain metals in the transmission system can react with the fluid, leading to a purple discoloration.
Is Purple Transmission Fluid Normal?
No, purple transmission fluid is not normal. It indicates an underlying issue that needs to be addressed. Ignoring purple transmission fluid can lead to costly repairs or even transmission failure.
How to Check Transmission Fluid
To check the condition of your transmission fluid, follow these steps:
- Park the vehicle on a level surface.
- Shift the transmission into neutral.
- Locate the transmission fluid dipstick (usually near the engine).
- Pull out the dipstick and wipe it clean.
- Reinsert the dipstick and pull it out again.
- Check the fluid level and color.
What to Do if Transmission Fluid is Purple
If you notice that your transmission fluid is purple, take the following steps:
- Stop driving the vehicle immediately.
- Check the fluid level and color.
- If the fluid is low or contaminated, call a mechanic.
- If the fluid is at a normal level and is not contaminated, observe the fluid for any further changes.
Importance of Regular Transmission Fluid Changes
Regular transmission fluid changes are essential for maintaining the health of your transmission. The fluid breaks down over time, losing its lubricating and cooling properties. Changing the fluid according to the manufacturer’s recommendations helps prevent transmission problems and extends its lifespan.
When to Change Transmission Fluid
The frequency of transmission fluid changes varies depending on the vehicle and driving conditions. Consult your owner’s manual for specific recommendations. Generally, transmission fluid should be changed every 30,000 to 60,000 miles.
Types of Transmission Fluid
There are different types of transmission fluid available, each formulated for specific transmission systems. It is crucial to use the correct type of fluid for your vehicle. Refer to your owner’s manual for the recommended transmission fluid specifications.
