My local Toyota service center has a machine that will remove most if not all transmission fluid.Is anyone familiar with this process? I have read mixed opinions on whether it is safe for a CVT.I just think it is a waste of time to pay 2-300 dollars for a partial fluid change when maybe only a couple Quarts comes out.

I’d stay away from the flush machine. Contamination is the worse enemy and will be in your clean fluid. Just do drain and fill service as it’s safer than getting someone else’s junk.
Yes, I have heard and used such a machine at the dealer. And it works perfectly. Currently at 175k.

150k transmission flush
2010 LE J-Vin with 150K miles, completed a Trans Flush today at the dealer (260$ out the door). Never touched the transmission since we bought it in late 2010. Just putting this out there for folks hesitant to flush because of high mileage. Car runs perfectly fine, shifts at 10, 20, 25 and 35...

Toyota has caused too many headaches with their CVT transmission and there is still no solid answer on how to maintain it properly.
Owners manual states to replace CVT fluid at 60k miles under extreme conditions (which is most of us that live in the city or hot areas). But dealerships can't actually perform that properly or don't want to do it at all.
-Doing a drain and fill and a filter replacement isn't a cvt fluid "change". It's a %50 change.
-If you take it to the dealer for a "change", it's more like an %80 change WITHOUT the filter replacement (if the flushing machine is used).
Does the dealership "flushing" machine allow the 4 quarts to drain out first and then it injects 8 fresh quarts afterwards? Does it recirculate and filter your existing oil? Or does it just pump 8 quarts in immediately as 8 quarts drains out and mixes it all up? Nobody knows...
If you decide to do a drain and fill yourself every 60k miles with a filter replacement, and utilize the pin #4 and #13 jumping method on the obd2 port, there is still no solid shift sequence to perform to get the car into fluid leveling/maintenance mode. Every youtube video has different instructions. So at that point, are you supposed to just use an OBDII scanner to measure the transmission temp via the ECU and trust that and have a friend sitting in the drivers seat reading you the temp as you are draining the fluid underneath? Are you supposed to use an infrared thermometer on the transmission pan? Nobody knows. There are far too many variables for the DIY method to perform the job with %100 confidence.
And then there's the question of how much underfilled/overfilled does the transmission have to be to start acting up or for damage to be caused for those that simply want to drain fluid and refill the exact amount without performing the fluid leveling proecedure? Is so sensitive to the point where only a few spoonfulls low or high can cause issues? Or is it in the range of up to a half quart? Nobody knows.

All dealers and most if not all small shops have a machine that can exchange oil thru the oil lines running from the transmission to the radiator and back. It does this by tapping into the oil lines and connecting those to the machine.
Not all vehicles can make use of that machine.
My 2014 has a heat exchanger mounted to the front of the transmission that has coolant lines running from the radiator and back. Tap into those lines and you will be exchanging coolant from the radiator with whatever is in the machine.
If your car is like mine... That will not work.
