My car has 162000 miles.
My car has an automatic transmission.

Hi there - this transmission (5L40E) has problems with valve body wear in higher mileage vehicles that can manifest itself in some of the behaviors you describe. This is due to hydraulic pressure not being high enough for complete, rapid gear engagement and proper shift behavior. I would recommend a thorough transmission inspection of the hydraulic circuitry (valve body and solenoids) to confirm that this is the problem, and that transmission clutches are not damaged. Unfortunately, this is not a service YourMechanic offers at this time. Seek out a reputable transmission shop in your area for this diagnostic service.
