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.

I added Lucas tranny additive, cuz my tranny slipped really bad from 1st to 2nd, It helped quite a bit, but still, my car has 171k on it, and the Aamco people talked like it was the original tranny, it did help quite a bit cuz it doesn't slam as often and stuff, but it hasn't made it great shifting, I would reccomend it to help it, but its not gonna eliminate all ur tranny problems, so if you plan on keeping the car, I'd reccomend trying to find out what the problem is with the tranny, rather than use an additive, cuz once you get it flushed and such, the problem will be there right where you left it.
