Yes. 40-60K Kms is the normal change interval (it can be less or more in some cases, and also varies from car brand to brand, model to model, etc.)
I don't know what's the condition of CVTF in my ride, and I plan on changing it at 25K Kms IN SHA ALLAH. After that, may be, the change interval is after every 40-60K Kms, but depends.
You may go for Toyota Genuine CVTF 4L Tin pack, otherwise, other better and compatible options are also there.
I will be using CVTF by Caltex Chevron, and details / pics are mentioned in some of the early posts above (you can check).
