How do I know if I need a transmission additive?

Yes, there are specific transmission additives formulated for different types of transmissions, such as automatic, manual, and continuously variable transmissions (CVTs). It’s important to use an additive that’s compatible with your specific transmission type.
How often should I use a transmission additive?
Usage frequency can vary depending on the product and the vehicle’s condition. Some additives are designed for one-time use, while others might be part of regular maintenance. Always follow the manufacturer’s recommendations.
Can transmission additives be used in old vehicles?

Do transmission additives really work?
Many users report benefits from using transmission additives, but results can vary. They are generally more effective for minor issues and preventative maintenance rather than fixing major mechanical problems.
Can I mix different brands of transmission additives?
Mixing different brands or types of additives is usually not recommended as it can cause adverse chemical reactions or dilute the effectiveness of the individual products. Stick to one product unless otherwise specified by the manufacturer.
Can using a transmission additive void my vehicle’s warranty?
