I have a 2013 gt with 31,000 miles. I just replaced the stock clutch with the Exedy mach 500 clutch. After getting the car back from the shop I had 10 or so codes. I used my sct x4 to conduct the crank relearn but the codes keep coming back and the car runs rough. The codes are as followed p0010, p0013, p0020, p0023, p0135, p0141, p0155, p0161, and p0443. if anyone has some info to help me out that would be great.

 

I didn't look up the codes but to me, I would think they might have pinched a wire or 2. If you can, get the car on a lift and check the wiring around the bell housing. good luck

 

In addition to what said above, it is also possible if they disconnected something and didn't connected back together. That has happened to me before. As it is said, would be helpful if you can get under there and check all the wiring and connections.
Good luck

 

Most of those are O2 sensor codes. There are pinched O2 wires or they damaged the sensors themselves when installing the clutch. Get under it and take a look, should be easy to find the damage. The shop that did the work must employ a bunch of hacks.
