Gears shiftlng hard, code 00453

My car drives fine after being started for the first time each day and I am able to drive at a consistent speed down a highway for a few hours, but as soon as I come to a stop after driving for a consistent speed for a while and begin to accelerate, the car takes a while to shift gears and doesn’t shift until the rpm's reach a higher than normal range. Once the gears do shift, they shift with a heavy jerk.

The code that the reader presents is 00453 which states that the transmission is overheating.
