Changing the transmission fluid in your 2018 Honda Civic is one of the most important maintenance tasks you can perform to keep your car running smoothly and extend its lifespan. Unlike older models, the 2018 Honda Civic uses a sealed automatic transmission that requires a specific procedure—called a “drain and fill”—to properly service the fluid. Doing it wrong can lead to costly repairs or even transmission failure. In this guide, we’ll walk you through everything you need to know, including the best fluids, tools, and products to make the job easier and more effective.

Customer Reviews
Customer Review: “If you have a first generation Honda CVT then do not use anything else except this. I didn’t listen to everyone saying to only use genuine Honda CVT fluid and bought another brand which stated it would work. Sure, the other brand didn’t ruin my transmission but it would occasionally slip a little. I wish I would have just spent the extra money and used Honda fluid.”
Customer Review: “I bought this looking at the label and saying it was for all Honda CVT transmissions. Then got under my car and saw the sticker that says HCF 2 on the label directly next to the fill hole in the transmission. Mine is a 2016 fit with the second generation CVT. Make sure you get the right fluid. The good news is that this fluid is compatible with my transmission, but it’s not for all CVTs—read the fine print!”

Customer Reviews
Customer Review: “I have a 9 yr old Murano with 130,000 miles on it. Recently found it would hesitate, (significantly) when pulling away from a complete stop and when the engine was warm. Best way to describe it it trying to pull away in third gear in a stick shift! Took a long time to get moving! Had the plugs and lines flushed and replaced with Honda fluid. Added this product and the hesitation is pretty much gone. Definitely recommend this product.”
Customer Review: “This is not a miracle product but it does help hot CVT transmissions perform better by reducing foaming. If you are using Castrol Transmax this is a must have additive! Some advice: Your best bet is to change the fluid and filters first. If your vehicle has a pleated paper filter, usually underneath the pan, consider replacing it too.”
