I was up for a CVT fluid drain and refill on my 2009 Nissan Maxima. The car has 200K miles on the original CVT (yeap original CVT). Upon checking the fluid, it was really dark and needed to be replaced. Typically, I use Nissan OEM CVT Fluid.  The non-OEM fluid is usually not recommended given the sensitivity around the CVT transmissions. But given my car is way out of warranty and I might need a CVT replacement anyway, figured I’d give the Castrol Transmax CVT a try.

Castrol Transmax CVT has good reviews and hasn’t seen any reports of damaged transmissions. Also, most of the people who have had transmissions issues used Nissan OEM Fluid (so not so much of a fluid issue). Not to mention that it was on sale for only $5 bucks a quart and available locally.

Update 11/19/2019: After driving approx. 20K miles, the car is still driving smooth and perfect. The car has 212,806 miles on the original CVT. 

Important Note: If your vehicle is still under Nissan’s warranty, and you don’t want any hassles should you have a transmission issue, don’t use this product. Not because it’s not a good product, but because it is RED just like regular transmission fluid. You’ll have a heck of a time proving that you actually used an OEM Nissan fluid.
