What to Do When You Put the Wrong Transmission Sealer in Your CVT Transmission

Accidentally putting the wrong transmission sealer in your CVT (Continuously Variable Transmission) can be concerning, but with the right steps, you can prevent potential damage. This guide provides a comprehensive approach to addressing the situation effectively.

Immediate Actions: Do Not Drive the Vehicle

If you realize the mistake before starting the engine, do not drive the vehicle. Driving with the incorrect fluid can cause significant issues as the engine circulates the wrong fluid.

Consult the Owner’s Manual

Refer to your vehicle’s owner’s manual for specific recommendations regarding the correct transmission fluid or sealer. Understanding the required specifications will guide your next steps accurately.

Drain the Incorrect Fluid

If the incorrect sealer has already been added, you will need to drain it from the transmission. This typically involves either removing the transmission pan or using a drain plug depending on your vehicle's design.

Flush the Transmission if Necessary

In some cases, a full flush may be necessary to ensure all of the incorrect sealer is removed. This can be done using a transmission flush machine or by following procedures outlined in the service manual.

Add the Correct Sealer/Fluid

Once the incorrect product has been drained, refill the transmission with the correct fluid or sealer as specified in the owner’s manual.

Check for Leaks

After refilling, check for any leaks and ensure that the transmission is operating smoothly. This step is crucial to prevent further issues.

Monitor Performance

Monitor the vehicle’s performance closely for any signs of problems, such as slipping, overheating, or strange noises. These issues could indicate that the incorrect sealer was not fully removed or that other components are damaged.

Consult a Professional

If you are uncertain about any part of the process or if you notice any problems after the correction, it is best to consult a professional mechanic. They can perform a thorough inspection and ensure that your transmission is functioning correctly.

Taking these steps can help mitigate potential damage to your CVT transmission caused by the wrong sealer.

Depends on the Makes and Models

When dealing with transmission issues, the results can vary widely depending on the make and model of your vehicle. For certain models, such as Honda, you may face significant issues. If you made a mistake or are unsure about the process, don’t hesitate to seek professional help.
