I have a 1998 GTP, and recently i found that my performance shift won't engage. I have a DHP 1.0 pcm, which makes the performance shift much more noticeable. The clicker on my shifter doesn't do anything, and the light never comes on (for the 1998's the perf shift indicator is a blue words on the dash, not under the boost guage) I'm about 90% sure that it's stuck off and it isn't just the light not working, i can feel the shifts are not as stiff. Not sure what to do if anything can be done
