My car has lost power. The gears have been getting a little stuck lately. Is it the transmission?

What is your question?

My car is losing power. I was told the transmission and by another person said it is the ball bearings. What could it be?

What makes this problem better or worse?

It just stays like that. Maybe a little low on fuel it gets worse

How long has your 2006 Ford Five Hundred had this problem?
