Smooth Shifting and Great Quality Fluid
This transmission fluid works exactly as expected. I used it for a fluid change and immediately noticed smoother shifting and quieter operation. It’s nice having a universal ATF/CVT fluid that works for multiple vehicles, so I can keep one jug on hand for different jobs. The gallon size is convenient, and the quality of Castrol products never disappoints. No leaks, no slipping—just consistent performance. Definitely worth the price for reliability and protection.

Perfect transmission fluid for My Nissan Maxima 2018 CVT
Perfect transmission fluid for My Nissan Maxima 2018 CVT I’ve used Castrol Transmax ATF/CVT Universal Automatic Transmission Fluid on my 2018 Nissan Maxima, and it’s been excellent. After the change, the CVT felt smoother, with seamless acceleration and no hesitation. The driving experience became noticeably quieter and more consistent. If you have a Nissan CVT that needs frequent servicing, this fluid fits the bill. It’s convenient to keep on hand, works reliably, and the 1-gallon jug is the right size for a complete service without leaving you short. The pour is clean and controlled, which helps avoid messy spills in the driveway. I still recommend double-checking your owner’s manual to confirm compatibility, as some transmissions can be picky about fluid type. But for my Maxima, it’s been a great match. Bottom line: For Nissan CVTs that need regular maintenance, Castrol Transmax delivers smooth performance, good value, and dependable results every time.

Castrol has always worked well for me. I use it all the time!
Good quality transmission fluid. Says it meets my manufacturers requirements so that helps. Looks alot better than my old fluid did. It's really nice to use a larger container versus several small quart sizes, makes it easy to change out.

As good as it gets!
It just works! What more can you ask for in a transmission fluid? Nissan dealer told me if I did not heed their recommendation and use their costly, original CVT fluid, my CVT transmission would disintegrate into a nether realm. So, I accept their challenge and refuse service, and I did it myself. I bought 2 of these and ended up having to just use 1 so far. After using this fluid and almost a thousand miles of driving, I must say that Nissan dealer is full of themselves! I will update you if my CVT transmission blows up because I am using this fluid! Arguably, after filling with this fluid, my CVT transmission runs smoother than before! NO issue shifting at all.

I did a three fill and drains on my daughters HR-V. Transmission performs great and much better after using the Castrol.

Off brand full synthetic with more frequent changes is the way to go
I saw many YouTube videos where people have been using offbrand transmission fluid for a long time. I made the jump because Honda and Toyota fluid was way too expensive. I also really want all of the fluids I replaced now to be fully synthetic. On top of that this was cheaper than anywhere local. One of the two bottles was damaged in shipping and the bag they came in dripped but I didn’t lose too much fluid.
