'00 Accord A/T - Doesn't Shift When Cold

Hi
My father's Accord shifts with some hesitation when it's cold. Once it warms up, seems to shift OK. Cold, it sorta hesitates to shift or gets a bit hung up during a shift if going around a corner. Engine kind of over-revs then shifts

He says he had someone run codes on it some time ago showng a tranny issue. Don't know exactly what.

Any input on culprit, cost, etc...

THANKS

What are the conditions of the ATF? Any service for tranny fluid in the past?

Does it whine when cold?
