You have to have the truck running and up to temp anytime you try and pull the higher of the two plugs to check the fluid level. The temp is supposed to be between 95 and 135 degrees F. when you check it. Same way when you fill it.

Put fluid in till it comes out on you then start it and let it warm up, add fluid as it will allow and once up to temp, run it through the gears while holding the brake and then check and see if you can add more fluid.
