How to Remove the Auto Shifter Button on a VT VX VU
You are going to need to remove the center console to get to a pin you need to get out to change the button.
First off, you need to remove the 2 screws either side of the Cigarette light

Then you need to remove the surrounding bezel, it has 3 points it is clipped in, the back surround brakes every easy so be careful when get it off, i found a small screw driver from the side points and my fingers to carefully pry it up. Once you lift the back about 20mm you will need to get you figures in under it to pop the Window Controller out. It will have a connection you need to unclip and it will pop out. Now put the car in to 1st gear and lift the surround off and out the way.

Next you need to get the Console out, first off you will need a 10mm socket with an extention to remove the 2 nuts under the arm rest lid at bottom of console

On either side of the console, down near the seat rail there is a screw that needs to come out, now pull the panel down and out a bit. You will see it is an extra flap hiding another screw

Now you should be able to lift the console out, lift from the back making sure the car is in first, a little wiggling and it should come out...
Now under the Shifter plate is a metal shaft with a pin going through it, we need to take it out. I found a 4mm pin which was perfect size to press it out. When getting the pin out you need to pres down on the Shifter button a bit to locate it properly. You will see it disconnected the Trac Control for a bit more room.

Last thing to do is take out 1 screw at the front of the shifter, so put it in fist gear and remove the screw, then put back in park.
The Whole Gear Shifter and Button will come out in 1 piece.

To put it all back to together is the same in reverse, i used a pair of pliers to get the pin back in twisting and turning a bit to get it going back in.
