Correct. And with good reason.I'm surprised by the motor oil posts 'any name brand full synthetic' is OK, but lots of people are hesitant on CVT fluid
Transmission fluid is quite different from motor oil. The fluid's friction characteristics, viscosity, etc, all come into play when the valve body is sending signals around the internal components, telling the unit how to function. Aftermarket fluid, even if it meets the approved "spec" is different, and all bets are off regarding long term effectiveness.
