    Its probably the speed sensor on the trans or the wiring for it. The ecu needs to see the signal from the speed sensor on the trans in order to allow the car to rev past 5k.

    Make sure you check the wiring before ordering a new sensor unless you'd rather just buy a new one, those wires can get chewed up by road debris and the like.
