Are you smoking something?
You say that all ATF are the same, then why not use regular ATF in CVT??? ATF is not just oil, its got a lot of friction modifiers in it that are blended to a specific specification in order to make a transmission work like it should. Your trans relies on fibre based clutches holding to work, CVT do not, it has a metal belt - friction requirements are different.
Dont try to advise this idiocy to use CVTF in a shifting trans,
Toyota T-IV (JWS 3309) is available in Pakistan from Mobil Askari Lubes - click to see yourself.
The WS is also available and is a low visosity ATF for fuel economy - both WS and T-IV are used for shiting automatic transmissions. Choose as the requirement says.
CVT-TC is only for CVT units and should never be used in shifting trans, both static and dynamic friction properties are very different than ATF. ---- meaning you will seriously hurt your transmission. Your transmission works by stalling different clutch packs. The CVT fluid is not blended for that.
Can you share which sort of "experts" you have consulted who approved to use CVT fluid in a shifting trans? If those experts can provide you proof of their "suggestions" you can get incredibly rich by suing toyota motor corporation Japan.
