My 1997-2002 Fords/LIncolns always check the level hot while in park, after shifting slowly through each gear selection. Level should be low on the cross hatched area or below it when cold (engine running). Mine only goes up about 1/4 to 1/2" on the dipstick from cold to hot. If you check it engine off, it will be WAY up on the dip stick, about 1" above the full mark. Emerg brake is all mechanical and not part of the transmission system. You might have something mechanical failing in your transmission if such a small amount of fluid change causes shifting issues. It may not be the fluid. It could also be that your fluid is old and spent. What color is it?
For verification I always check both sides of the dip stick. I find it easier to read the back side for fluid line. If the engine is slightly warmed up, you should get a reading in the X-hatched area of your dip stick....assuming you have normal level to begin with.
