It's likely transmission has a major internal problem that has forced it into limp-home mode. When that happens, you usually have one forward gear and, maybe, reverse. This is why it will only go into first and / or reverse. Like as not, the clutches, bands, possibly the torque converter, and gears are worn. The transmission pressure control solenoid may fail also causing erratic shifting.
