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.

Save money while buying longevity
I drive a 2016 Honda CRV with a CVT. Currently has 271K on the odometer. This product is a life saver. Much more cost effective than the HONDA OEM fluid. Hasn't failed me and the CVT is still shifting like new. I change the fluid every 30-50K. Highly recommended.

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