Corolla CVT whine

[chmino]

Hello everyone

Have a problem with my 2014 Corolla 1.6 VVT-i CVT transmission 180000 km

It's a noise in the gearbox when accelerating disappear when rpm goes down.

I tried to fix it with changing the fluid completely with the special machine, rinsing replace a new filter and filing a new fluid.

But didn't feel any changes, any help?

That sounds like a scan tool job to me.
