2012 Ford Fusion SE transmission issue?

A while back I started driving from a complete stop and my car wouldn't shift to a higher gear. I pulled over, made sure I was in drive not low, put the car in neutral and attempted to drive again. It drove and shifted however the car seems to have less power and shifts later than before this happened.
Any idea why this happened, and/or if I need to have a repair done and what that repair would be?
The car has almost 87,000 miles.

Hi this sounds like case of someone who has no idea what a gearbox is for.

A "while back?" Very nebulous. Any idea "why this happened?" Really? "What the repair would be?" Triple really? Do just refuse to use professional auto repair technicians?

And what is more reliable and cheaper to maintain?
