How to Add Fluid to a Sealed Transmission

A sealed transmission is designed to be maintenance-free, and it doesn’t require regular fluid checks or changes like traditional transmissions.

However, there may be instances where you need to add fluid to a sealed transmission, such as in case of a leak or during a repair.

In this article, we will walk you through the step-by-step process of adding fluid to a sealed transmission.

What You Will Need

Before you begin, gather the following tools and materials:

• Sealed transmission fluid (check your vehicle’s specifications for the correct type)
• Funnel
• Jack stands or ramps (if necessary)
• Safety goggles
• Gloves
• Rags or paper towels

Adding fluid to a sealed transmission is a relatively simple process. However, it’s important to gather all the necessary tools and materials beforehand to ensure a smooth and efficient process.

Here’s a breakdown of what you’ll need:

It’s crucial to use the correct type of fluid specified for your vehicle. Check your owner’s manual or consult with a professional to determine the appropriate fluid.

A funnel will help you pour the transmission fluid accurately and prevent any spills or leaks.

If needed, use jack stands or ramps to elevate your vehicle and access the transmission area more easily. Make sure to position the vehicle securely before proceeding.

Protect your eyes from any potential harm by wearing safety goggles throughout the process.

Wearing gloves will safeguard your hands from any fluid or debris and provide a better grip on tools.

Rags or paper towels: Keep rags or paper towels on hand to clean up any spills or drips during the process.

Step 1: Safety Precautions

Before you start working on your vehicle’s sealed transmission, it’s crucial to prioritize safety. By following these safety precautions, you can ensure a secure working environment:

Park on a level surface: Park your vehicle on a level surface and engage the parking brake to prevent any accidental movement while you work.

Allow the engine to cool down: Give the engine enough time to cool down before you begin any work. This will help prevent any burns or injuries caused by hot components.

Wear safety goggles and gloves: Protect yourself from potential harm by wearing safety goggles to shield your eyes and gloves to safeguard your hands.

Step 2: Locate the Fill Plug

To add fluid to a sealed transmission, you first need to find the fill plug. The exact location of the fill plug may vary depending on the make and model of your vehicle. Refer to your owner’s manual to determine the specific location and instructions for your vehicle.

Locating the fill plug is essential as it allows you to access the transmission and add fluid accurately. Taking the time to find the fill plug will ensure a smoother process later on.

Step 3: Prepare the Vehicle

If necessary, you’ll need to raise your vehicle using jack stands or ramps to access the transmission. This step may not be required for all vehicles, especially if the fill plug is easily accessible without lifting the car.

If you do need to raise the vehicle, make sure to position the jack stands or ramps securely to prevent any accidents or injuries. It’s important to create a stable and safe working environment before proceeding.

Step 4: Open the Fill Plug

Using the appropriate tools, carefully open the fill plug. Keep in mind that the fill plug may be tight, so use the necessary force to loosen it without causing any damage. To avoid any mess, place a rag or paper towel underneath the fill plug to catch any potential drips.

Opening the fill plug is a crucial step as it allows you to pour the transmission fluid into the sealed transmission. Take your time and be gentle to ensure a smooth process.

Step 5: Insert the Funnel

Once the fill plug is open, insert the funnel into the fill plug opening. Make sure the funnel is secure and properly positioned to avoid any spills or leaks. A properly positioned funnel will help you pour the fluid accurately and prevent any unnecessary mess.

Step 6: Add Transmission Fluid

Now it’s time to add the sealed transmission fluid. Slowly pour the fluid into the funnel, taking your time to prevent overfilling. It’s important to refer to your vehicle’s manual for the recommended fluid capacity and type.

When adding transmission fluid, it’s crucial not to mix different types of fluid, as this can lead to damage. Stick to the recommended fluid specified for your vehicle to ensure optimal performance and longevity.

Step 7: Check the Fluid Level

After pouring in the fluid, allow it to settle for a few moments. Then, remove the funnel and reinsert the fill plug. Wipe off any excess fluid from the surrounding area to maintain cleanliness and prevent any potential leaks or drips.

To ensure the proper fluid level, start the engine and let it idle for a few minutes. This will help circulate the fluid and ensure an accurate reading. Check the fluid level using the appropriate method specified in your owner’s manual.

Step 8: Double-Check for Leaks

While the engine is running, carefully inspect the area around the fill plug for any signs of leaks.

Check for any fluid drips or unusual wetness around the plug. If you notice any leaks, tighten the fill plug further or seek professional assistance to prevent any potential damage to your vehicle’s transmission.

Step 9: Lower the Vehicle

If you raised the vehicle using jack stands or ramps, it’s time to carefully lower it back to the ground. Ensure that the vehicle is stable and secure before moving on to the next step. Taking precautionary measures while lowering the vehicle will prevent any accidents or injuries.

Step 10: Clean Up

Once you have completed the fluid addition process, it’s important to clean up properly. Dispose of any used rags or paper towels in a responsible manner. Seal the transmission fluid container tightly and store it in a safe place for future use.

Maintaining cleanliness and tidiness will not only promote a safer working environment but also contribute to the overall longevity and performance of your vehicle.

Conclusion

Adding fluid to a sealed transmission may seem daunting, but by following these step-by-step instructions, you can safely and effectively complete the task. Remember to consult your vehicle’s manual for specific guidance and always prioritize safety.

If you encounter any difficulties or are unsure about any steps, it is recommended to seek professional assistance to avoid any potential damage to your vehicle’s transmission.
