Take the car for a run of 5-7 miles to get the transmission nice and warm and the fluid well circulated and then drain it. Be careful of the hot fluid though!
I like to decant the drain pan into an empty, clear container such as an old 5l screenwash or antifreeze tub.
That way i can put it to one side and let it settle and see what dirt falls to the bottom after.
It's also easier to see the true colour of the fluid, a good way is to dribble some fluid onto a plain white kitchen towel as this shows up any dirt held in suspension as well.  :d |
