Transmission Shifts Hard From 1st To 2nd Gear

I am driving a '99 Vulcan Taurus with 71k miles. A year ago (10k ago), I noticed a somewhat unusually quick shift from the first to the second gear at low speeds. Gradually it became worse, and now it jerks and shifts really hard. It only happens when I am driving really slow in the first gear without touching the gas pedal or when I'm going down the hill from a stop. Other than this, the tranny works just fine.
The tranny is AX4S, I know it's AXOD's twin, the fluid looks fine and the fluid level is OK too.
Planning to bring the car to a tranny shop for a checkup.
Did anyone have similar problem, and what was the fix?
Any input is helpful.
Will let you know the results after I visit the tranny shop.

This exact thing was happening to my car. From a stop letting off the brake and coasting done a slight hill with foot of the excelerater it would come out of first slight hesitation then slam into second, and also some rough done shifts coming done to a stop. I had a complete trany flush, filter, and conditioner service done at the end of the summer and the transmission shifts are much improved. Were ever you take it I would stay there and watch them do it to make sure you get a complete flush. These cars are a slight pain to do because the battery and tray needs removed to access the lines that get hooked up to the machine then the battery needs hooked back up to do the service then disconnected then re installed (got keep them honest) I think Aamco offering a$100 special on the complete service. Although I don't think I would trust them to do a rebuild but flush maybe.
If you have not had the trany serviced in 71k you are over do
