Yes, it could be low in ATF oil. Maybe an oil and filter change will sort it. Good luck with the buy

other than that, the gears inside could be worn, but it you don`t hear any wierd noises i think it`s ok ....

I had this problem, changing the pump and converter didn't solve it.
A year after i cleaned filter and changed oil, problem not gone (cleaning filter not exactly a good idea ;) but the car went forward again after that )
Some time later i lost reverse, and low gear brake, that time i took the auto down and changed around 4 clutch packs, filter and oil after that problem was gone.
But it could be a good cleaning of the inside that fixed it, you could try flushing the system? Then do a filter change.

Clutch packs can wear out prematurely in these boxes. They don't like being left in "P" or "N" for any period of time.
Sometimes they can play up if the fluid is old, or low.
Best thing to do is look for a low mileage used box, and keep this in the garage in case of failure. The box in the car you're looking at may go on like it is indefinitely. A fluid and filter change is worth doing, but due to the costs involved with recon box's, i wouldn't throw any more than that at it.
Its not too bad a job changing out a box, and if the rest of the car is good, it may be worth a punt. Make sure you haggle well though, and tell him the box is kippered!

After letting the gearbox drain of its fluid, remove the bolts around the pan of the transmission, and slowly lower it down. Be prepared for some mess.
Look up into the bottom of the gearbox and the filter is the first thing you see, smooth, flat, silver metal thing. Its held on with a couple of screws. Undo them and remove the filter. Check that the sealing ring has come away too and is not still attached to the gearbox.
Replace filter with new sealing ring, and replace gasket on the transmission pan. Bolt back together.
Its important to keep the area around the transmission clean, so its a good idea to give the area a good degrease before getting stuck in.
Measure the amount of fluid that drained out, and replace that amount with new fluid. Don't overfill, as this can make the transmission slip.
