Default 8 Speed 8PH70 Question
I am curious for those who own the 8 Speed.

After initial break in-->How many have actually drained the pan and added fresh fluid?

I assume within the plastic black finned pan that some what drain plug looking item is actually a drain plug for the 8PH70?

If any of you have actually drained this pan-->How many quarts actually drain out from the pan?

I have plans on doing this around the 10K mile mark.

Yes I know this does not actually drain {ALL} the fluid from the transmission.

I am just curious how many quarts actually drain from the pan itself.
