Yes sir the work was done at dealership. And what they did was very simple.
Remove the drain plug, take out all the CVT fluid and put it back in.
I was present there, if i am not wrong .25 litre CVT fluid was wasted which i am worried about.
Now 1.8 grande does not have a dipstick to check the fluid level. and concern is since a little of the fluid was wasted should i consider whole of the CVT fluid replacement or should i be satisfied as toyota guy said its ok if you waste such a little fluid.
