Next cut away the carpet covering the shift cables. Make sure you cut wide enough to get to the bolts that hold in the shift cables.
Then you can remove the shifter cables from the shifter base
Pry them off the shift tower itself and then untwist the knobs holding them to the shifter base. Pull up after you have untwisted them enough.
Unbolt the two bolts holding down the rubber seal. Now it's time to get under the hood.
Remove your airbox and your fuse box. Mine just pop off when you pull on them. Supposedly not all of them are like this.
Then you need to pop off your old shift cables.
If you look in the picture you can see that the rubber bushing is still stuck on
This isn't all that easy to get off. I cut off all the rubber with wire cutters. Then I used two screwdrivers to pry off the metal part which was still stuck on. I had to pry on both sides simultaneously or it wouldn't come off. It took me a while to figure this out. Then pry off the other cable end. I used a pry bar and it came right off.
Now comes the fun part. You can try to untwist the knobs holding on the cables with your hands, but unless they are super strong and super small at the same time it won't work. Attach the vise grips to the knobs and untwist them with the vice grips. You will need to twist them and unlock the jaws and twist again several times if you shift cables are like mine. Do the top cable with the black end on it first. The picture shows on the white cable what I did.
Your shift cables are now free!
You can now go in the car and start pulling them out. However, if they are like mine, they will get stuck on the exhaust shield, since there is a protective metal shield over them with lots of ridges on it. To get rid of this problem, go underneath and move the exhaust heat shield out of the way. You may need to drop the exhaust to do this. I did not have to because my exhaust support is broken. Your cables should now pull free.
Installation is mostly the reverse of removal, but you need to careful of some things. When you put the knobs into their support there is a little plastic ring in between. It helps keep the knobs from closing down on you while you are putting them in. It comes off after they are installed, so don't worry about that. You also need to make sure that the orange button protrudes from the shift cable end. In this picture the button in the white end is correct and the one in the black end isn't. If just the white one is protruding you may not have reverse, at least I didn't.
If you don't do this it will become disconnected like this
To adjust them follow S2's method listed here
. It really helps to have another person when you are doing this. Then put everything back, unless you want to delete your armrest or something (I like no armrest). Now you are done
