What type of fluid do I put in my transmission?
Choosing the correct transmission fluid for your vehicle is crucial for maintaining its performance and longevity. Transmission fluid acts as a lubricant for the moving parts inside your transmission and helps regulate temperature. Using the wrong type of fluid can lead to costly repairs and reduced efficiency. In this article, we’ll guide you through the basics of selecting the right transmission fluid for your car.
Understanding Transmission Fluid Types
Transmission fluid comes in different types, and the correct one for your vehicle depends on the type of transmission it has. Here are the main categories:
- Automatic Transmission Fluid (ATF): Designed for vehicles with automatic transmissions, ATF provides lubrication, cooling, and hydraulic pressure for smooth gear shifts.
- Manual Transmission Fluid: Used in manual transmissions, this fluid is typically thicker and provides the necessary lubrication for gears and bearings.
- Continuously Variable Transmission (CVT) Fluid: Specially formulated for CVT systems, this fluid ensures the belt or chain operates smoothly within the transmission.
- Dual-Clutch Transmission (DCT) Fluid: Designed for dual-clutch systems, this fluid supports the unique needs of these high-performance transmissions.
Each type of transmission fluid is formulated to meet specific requirements, so it’s essential to know which one your vehicle needs.
How to Determine the Right Fluid for Your Vehicle
To find the correct transmission fluid for your car, follow these steps:
- Check Your Owner’s Manual: The owner’s manual is the most reliable source for determining the type of transmission fluid your vehicle requires. It will specify the exact fluid type and any manufacturer-approved brands.
- Look for Manufacturer Specifications: Some vehicles require fluids that meet specific standards, such as Dexron, Mercon, or other proprietary formulations.
- Consult a Professional Mechanic: If you’re unsure, a trusted mechanic can help you identify the correct fluid for your transmission. At Kevin’s Autos, we’re always happy to assist with such inquiries!
- Check the Transmission Dipstick or Cap: In some vehicles, the transmission dipstick or cap may indicate the type of fluid required.
By following these steps, you can ensure you’re using the right fluid to keep your transmission running smoothly.
Why Using the Correct Fluid Matters
Using the wrong transmission fluid can lead to several issues, including:
- Increased Wear and Tear: Incorrect fluid may not provide adequate lubrication, leading to premature wear of transmission components.
- Overheating: The wrong fluid can fail to regulate temperature effectively, causing the transmission to overheat.
- Slipping or Hard Shifting: Incompatible fluid can disrupt the hydraulic pressure needed for smooth gear changes.
- Voided Warranty: Using non-approved fluids can void your vehicle’s warranty, leaving you responsible for repair costs.
To avoid these problems, always use the fluid recommended by your vehicle’s manufacturer.

Frequently Asked Questions
What oil can I use for automatic transmission?
Castrol TRANSMAX Dexron®-VI Mercon® LV Multivehicle
Suitable for use in most Asian and European automatic transmissions.
What is the best transmission fluid?
Recommended Products. Valvoline Dexron VI/Mercon LV ATF is the full-synthetic automatic transmission fluid that has been uniquely engineered to meet and exceed the requirements of the General Motors Dexron VI specification and is officially licensed and approved by GM.
How do I know what transmission fluid to put in my car?
You can find the recommended transmission fluid type for your vehicle in your Owner's Manual or you can refer to Ford's Chemicals and Lubricants website.
What happens if you put the wrong fluid in a transmission?
If you do not identify that you have been using the wrong transmission fluid in time, it is possible to suffer long-term effects. Driving with the wrong type of fluid can cause premature wear and tear of the transmission, issues with efficiency, and, unfortunately, high repair costs.
What kind of fluid do you put in a transmission?
Commonly recommended manual transmission fluid formulations include SAE 80W, 75W-90, 80W-90 and SAE 90. In some cases, a multi-grade engine oil or automatic transmission fluid may be recommended. However, a manual transmission fluid is typically the most optimal for manual transmissions.
Can you just add transmission fluid if it's low?
Of course, low fluid requires that it's topped up. If the fluid is lower than the minimum mark, add fluid of the exact type your owner's manual specifies. If in doubt, ask an AutoZone associate for assistance determining the right fluid, and they can also advise you on how to add transmission fluid.
What are signs of transmission fluid being low?
Along with gear slippage, low transmission fluid levels can also cause low levels of pressure, which leads to slower engagement when shifting gears. If you notice your transmission takes a second to engage when put into drive or reverse, it could be due to low fluid levels.
Can I use power steering fluid in my transmission?
It's never good to use power steering fluid in the transmission.
Does it matter what transmission fluid I put in?
So unless you're driving a car that's pushing 40, this isn't the type of ATF for you. Choosing the correct transmission fluid is critical to insuring the maximum performance and fuel economy from your car. Always check your owner's manual for the type of fluid recommended for your vehicle by the manufacturer.
Can I just add transmission fluid?
Insert long funnel into automatic transmission fluid dipstick hole. Carefully add automatic transmission fluid in small increments and recheck level each time until fluid level reaches "warm" line. CAUTION: DO NOT OVERFILL OR SPILL AUTOMATIC TRANSMISSION FLUID ON HOT ENGINE PARTS!
