Add Paddle Shifters to 13/14 automatics

For Automatic Owners of 2011 and 2012

For 2011/12 automatic owners, if you program the PCM to a 2013/14, then you will also need to upgrade to the Select Sport Shift automatic shifter. This is NOT plug and play, but is a real pain. Using the Black Box from Redlinersperformance.com is a better option here for automatic owners. If you go with the black box, then you do not need to mess with the auto shifter at all.

But if the PCM is programmed, on the old shifter, when you manually put the car into 1, 2 or 3, the cluster will show an error (a wrench symbol) that will need to be cleared using a diagnostic tool every time it comes up. It will shift normally, but the PCM is getting confused as it expects Select Sport Shift.

To correct this, get the Select Sport Shift automatic shifter box. You really only need the shifter **** with the button, but the old shifter bezel will still have the 1 2 3 on there, which is no longer used and will make the error message come up if you do shift into them. The new box will only show S only and not allow the shifter to move past the S. I also had to make a block and screw it into place to prevent selection of those gears manually using the shifter.

Also, hill assist is no longer functional - but you could just add it as an extra and put the button for it somewhere, like I did. It is redundant with the select shift anyways.

The wires from the **** will need to go all the way to the PCM at the front of the car. Thanks to Lex for getting the the info on how to route wires from the cabin to the PCM. It wasn`t too bad. The passenger side wheel and inner plastic wheel cover has to come out. Behind it you will see wires running from the passenger cabin all the way to the PCM at the front of the car. The wires going from the shifter have to go all the way to the PCM. You will have to push those 3 wires through the grommet in the firewall to get them through to the inner fender. A bit of a pain to do this, but this is the only PITA part.

Next I needed the connectors for C307 both male and female. These are on the shifter box and replace the ones that are there now. The current wires going into those connectors use larger pins, so I had to change them all out to smaller pins. Make sure you keep track of what you plug into the male and female connectors so that they match!!

The 3 wires from the shift **** are for select shift.

The white wire from the **** is for shift up and will go to pin 23 on connector C175B on the PCM.
The brown one is for shift down and goes to pin 24 on the PCM C175B.
The black wire is signal return and goes to pin 56 on the PCM C175B.

Once the wiring was routed to the PCM, I had to add pins to slots 23 and 24 in C175B as those slots are empty (The bottom of the 3 connectors in the PCM. Unplug them all to get access). The third wire I tapped into the wire going to pin 56.

You will now have functioning Select Sport Shift.
