So the DIY method seems to be the best route.

So in a nutshell:
Drain original fluid
Fill tank to max with distilled water
Drive car with heater on full blast. Get it up to temp and then do a couple WOT pulls.
Let car sit for a while
Drain fluid out
Fill with water again and repeat driving and cool down procedure.
Drain fluid out
Fill with 50/50 G05/distilled water mix to max level on overflow tank

Correct?
