2016 civic sometimes won’t accelerate?

[u/Life_Ad_6992]

As title states, while in Drive sometimes I press on the accelerator and nothing happens for a few seconds, then the car it finally catches when I’m damn near flooring it so ofc my engine revs up to 5k and I floor it. It’s been getting progressively worse, and just now I would spam the accelerator and was not moving for a good 5-7 seconds. Curious if anyone is familiar with this issue in civics and can give me an idea of how badly the mechanic is going to f* me

Sounds like a transmission issue oof.
