Problems with the shift-up light coming on 5th gear can be traced to a bad 5th gear/reverse switch on the back of the transmission.  If the transmission was recently serviced (i.e. clutch job) or engine removed, the wires could've been damaged or pulled off of the sensor.  The sensor is relatively cheap and easy to replace once you get under the car.

A working 5th gear/reverse switch would signal the ECU to not trigger the shift-up light after 2,200 RPMs.
