It's probably in limp-home mode giving you just two gears.

As Dan has written is might be your transmission control computer. The other
possibility is a faulty sensor that is monitored by the transmission control
computer. It would be instructive to know the code that the TCU
light-emitting diode is flashing. The module itself is probably under the
carpet under your passenger's left foot. It has a small window through which
the lamp may be seen. Don't confuse it with the adjacent engine control
computer.

Do a search in the Honda newsgroups for "TCU." That will lead you to some
details of diagnosis.
