Brake sensor. It tells transmission, brake is depressed and allows you to shift out of park. Or check with diagnostic computer, free at some major retailers. Most likely a sensor, if not transmission may be bad.
Sounds like more of a fuel problem to me.Check fuel pressure 35-40psi and or change fuel pump. Any was the car is equip with a TFI module which controls gas, spark and timing. Located in one or two areas. First spot is in the front of the car next to radiator passenger side. It will be gray in color about 3" long bolted in a heat dispactor. Spot 2 Drviers side of fire wall next to the master cylnder.
There is an electronic sensor on the outside of the transmission.Change the filter and fluid and replace sensor.The sensor costs around $150.
"High speed" probably is over drive,so if it is turned off,it can't engage.I have found that cutting the overdrive switch on and off can cause excessive wear and tear on the overdrive.
Regardless have the car scaned for a any codes thay is causing the problem. Just trying to keep the cost of repairs down by know exactly what the ECM has in it's memory for any malfunction that is creating your overdrive from engaging.
Good luck and hope this helps
