2011 Toyota IQ CVT Gearbox

[Camjohn98]

Good Morning, I was wondering if anyone was able to help. I have recently purchased a 2011 IQ and the gearbox is causing me some concern. When the CVT box gets hot and the revs increase there is a whine from the box. I have spoken to a few people who have told me it isn't possible to get any parts or overhaul kits for the internals of the box. Does anyone know of anywhere that can help with this please that may have the parts ready and waiting.
