I see no reason that the CVT couldn't be treated the same way many of us treat the 4EAT drain and fills.
- Drain fluid out
- Measure drained amount
- Refill with matching amount + a tiny amount to be left behind in the fill funnel.
Yes it does require software to read the temp and get the level set. However if one drains it cold and adds the same amount of room temperature fluid back in there is no reason the level should change by more than what clings to the funnel. If the system is that temperamental that < .5 oz of difference will change the behavior or function there is a serious design flaw, as our roads are not all flat and straight. The fluid in the sump is going to be thrown around as the vehicle corners, accelerates, goes up and down extended upgrades.
To me this is more of a gimmick/tool used to drive dealer services. I for one would have no issues doing a drain and fill every 10K to 15K and then popping into the dealer for a "level check" every other or third time.
I also don't buy into the "this CVT is assembled in a clean room". "Controlled environment" maybe, certified clean I find doubt full, unless it is close to a ISO 9 which is basically room air. Its a mechanical piece of machinery that functions on friction which causes wear resulting in those wear particles being suspended in the fluid, how clean does it really need to be.
Most would agree that a new engine needs to be clean when it is assembled. But many would be appalled at how clean it really isn't. Machining chips, fluid and even sand from sand casting of the block often times remain in new factory assembled engines.
