This is a DIY for automatic transmission with a OEM shifter handle not a aftermarket . Because a aftermarket handle if not adjusted correctly will act as if the shift lock control system isn't working .
This shift lock control system prevents you from taking your car out of park while it's running and prevents a child from accidently putting the car in gear unless you step on the brake pedal . Plus it will prevent you to take your key out of the car unless your vehicle is locked in park to prevent it from jumping out of park and rolling down the road .
How would you know if it's your shift lock control and not your transmission ? A simple test will determine that . You have a over ride button above the P . You stick a flat head screw driver and push the button down and see if your car comes out of park . If it does then your shift lock control system is not working . Spilling coffee or water or soda over time will short this out as in my case .
First you remove the frame around the shifter and the two screws on each side that hold the center console cover .
Then you put your parking brake on while doing the rest of the DIY . You carefully put the car in L3 by using the over ride button so you won't need the key in the ignition in the on position and then remove the center face but carefully pull it out slowly cause your lighter is still connected . Then you unplug your lighter and remove this . It's best to put black wire over your expose lighter wires cause when you test the shift control you do not want these wires to be exposed and hit any metal .
Then you open your glove box up and remove the three screws across the top . Make sure you put all your screws some where that you wont lose them .
Then with your 10mm socket you remove the bolt on the bottom left of the glove compartment box .
Then you pull the glove compartment box down and you will see another screw holder the center console . Again keep all your screws and bolts some where so you dont lose them .
Then you go to the drivers side and remove the bottom bolt above the gas pedal which holds the panel .
Once you remove that bolt then you unsnap the panel cover to expose the screw that is holding the center console .
Then you unscrew the middle compartment box because the screws are screwed to a metal brace and this will prevent you from taking that whole center piece out .
Then with a 12mm socket you remove the two bolts holding that back park of your center console . At this point you cant seperate the front piece from the back piece . Then you slide that over the parking brake . Remember your car is still in L3 so keep your brake up .
Then you can pull the center console towards you . It might give you problems but be patient look to see where it gets hung up .
Then you unscrew the two screws that hold the shifter cover . You can remove the handle to take this off completly but in my case all I did was raise it up and twist it out of the way to get to the shift lock system .
Then you unplug the shift lock control system and unscrew the two screws holding the unit down .
This is a very important reminder . Yes you can drive your vehicle with out this unit . But you are taking a chance your car can pop out of gear , you can shut your car off while in gear and remove the key , you can think you have your car in park and not know it , a child can easily change the gears , you can accidently hit it out of gear . So in my opinion your life isn't worth taking a chance not having this . This unit I have I removed from a geo prizm so they interchange . One is white the other is back thats the only difference .
Keeping your car still in L3 now you put back and screw down your new shift lock system and then plug it in . Once you have completed that then put your car in park . It should automatically lock .
Now you can put your key back into the ignition switch and turn the vehicle switch on but DO NOT START THE CAR . Only in the on position then with your hand push down on the brake pedal and then you should be able to take your car out of gear with ease .
Once you have completed your test remove the key and then you can put it all back together again .
