I think he is asking, once he installs the tranny cooler and remote filter, around how much extra tranny fluid should be used to keep things equal in the tranny. Not how much should drain out.

Once the tranny is warmed up and running you can check the level and add accordingly.

If you have empted the tranny fuild to install the cooler and filter, I would say once you have everything back together check the level, make sure you it's close to the minamum level on the dip stick, then start the engine and let things warm up and add accordingly.
