I have flushed/changed fluid many a times.
Done it once in my 98 vette.
Only thing different from this DYI shortcut is to remove the termostat. Just two bolts. Easy. Reuseable rubber gasket. Nothing to buy. Can flush system with water hose. Good thing to do. Also remove tranmission cooler lines. Hoses to water pump. Just connected by hose clamps. No parts to buy. You will be able to see the water hose pushing the old fluid out of the overflow tank.
This beats removing the engine block plugs. They are hard to get to.
It is real easy to get to and cost nothing.
