smithdjason Posted November 4, 2011 Report Share Posted November 4, 2011 hello all , i am new to this board and would like to say thank you in advance for any help given and i will try and help anyone as well. three days ago i purchased a 1999 buick rega LSl , it has 39,000 miles on it and it is in excellent condition. it has a light on for the performance shift showing it is on, in the manual it states there is a button on the shifter to turn this feature on and off. the is no button on the shifter and i can not find any way to turn this on or off. any one have any ideal how to turn this on or off ??? Thanks , Jason Quote Link to comment Share on other sites More sharing options...
digitaloutsider Posted November 4, 2011 Report Share Posted November 4, 2011 Performance Shift was a GS/GTP only thing. The only reason it should be illuminated is if someone grounded pin 21 on the PCM for some reason. Quote Link to comment Share on other sites More sharing options...
