Good Stuff!! All low speed shudder is gone.
Size: 5 Quart Jug
I have a 2020 Nissan Altima SL 2.5l and Nissan is VERY specific about using ONLY NS3 transmission fluid. There are only a couple NS3 transmission fluid manufacturers...Nissan NS3 (Manufactured by Idemitsu), Idemitsu (a little cheaper than Nissan dealer), Triax, and Mannol (works good too).
Seeing as Nissan is still using Jatco CVT transmissions which are known to be very troublesome, and very expensive to replace I wouldn't try any of the so-called "universal" transmission fluids just to save $50 and end up replacing a $6000 transmission.
The Triax fluid seems to work very good in my car. I don't feel the shutter that I normally feel when driving slow and need to accelerate. The shudder is completely gone and operating smooth.
The old fluid had 50k miles and it was very dirty but didn't smell burnt.
I ended up doing 2 - 3 1/2 quart changes with 200 miles between the first and second change.
I plan on doing another 3.5/4 quart change every 15k miles since there is no way to completely drain the 7.4 quarts of transmission fluid. The first change, only 3.5 quarts drained from the pan.
