You need a proper diagnosis from a transmission specialty shop. You still didn't tell me if the fluid level was checked with the engine running or off so I'm not ruling low fluid out. If the cause of the problem isn't obvious to the experts, they'll perform some pressure tests to get a better idea of what's happening. I don't know how many miles are on the vehicle either or what kind of maintenance history it has had, so it's hard to know what will be needed.
Generally I'm in favor of repairing older vehicles rather than buying something newer, mainly because the newer a vehicle is, the more unnecessary, complicated, and unreliable computers it has and the more it will cost for repairs.
