🔴 Red Line 30804 Non-Slip Continuously Variable Transmission Fluid - 1 Quart (Pack of 6): Unmatched Performance and Safety Review

CVTs are notoriously unreliable. When I saw the red line turn into a flowing "L," I knew it could be trusted. I used it to service my 100,000 mile Subaru Cvt and have driven 6000 miles since then. After reaching the operating temperature, it is quiet and "switches" smoothly. From now on I plan to service the Cvt with this fluid every 30,000 miles.

I can only speak from experience. My CVT started making noise and I changed the fluid and filter. I drew it in red and my transmission got 100x worse and shifted horribly. I bought some Nissan fluid and made another change. It sounded MUCH better but still didn't shift well than the transcode did. I did another fluid change with Nissan fluid and still bad. I'm not sure if Redline hastened the destruction of my CVT, but if you heard it after I topped up the Nissan fluid, you'd think it happened.

Overall, I've found Redline transmission fluids to work well in extreme cold and heat. In an old 4L60E that slid a little until the fluid warmed up, I drained and filled with D4 and never again had a cold slip problem in that car. Based on that experience, I decided to try it on a Nissan with 130,000 miles on the CVT. Nissan extended the warranty on these CVTs to 120,000 because they are notoriously junk and prone to belt slippage. I've drained and refilled a 100k Valvoline CVT (I usually liked
