Can too much transmission fluid cause hard shifting?

If you add too much transmission fluid, you will notice that it may foam, and that can bring about erratic gear shifting. Some other problems that may arise include oil starvation and transmission damage. Adding too much transmission fluid can also cause early failure and damage of parts as result of excess pressure.

How can I make my automatic transmission shift smoother?
