Bad clock spring
My car is at the dyno and the tap shift doesn't work, it worked fine before my build. I'm wondering if the steering wheel didn't get turned to many times when my steering rack was out. Is there any way to test the clock spring to make sure its not that? Iv checked fuses and they all look good.

you can disconnect the clockspring plug at the steering column, you would check for resistance on 2 wires when you push the paddles, I'm not sure what wires, I think Black and Blue or Black and Green but not 100%

Tech II, aim the tires straight ahead with the steering wheel, then check the steering wheel postion sensor to make sure it reading O.
If the steering wheel is spun one rotation out and the steering box coupler was reconnected, the Steering wheel position sensor will be not be reading O, but either a high positive or negative number instead. so high positive number means that the wheel was spun clockwise one rotation out, while a high negative number means that the wheel was spun one rotation out counter clockwise isntead. Hence steering column coupler will need to be disconnect, the steering wheel rotated one full rotation in the correct direction to zero the SWP sensor to Zero, and the column coupler reconnected.
If the steering wheel was spun more than 2 rotations from its SWP zero reading with it disconnected from the steering box in either direction, this is what killed the clock spring, and the clock spring will need to be replaced.

So tech II will only tell you if the steering wheel position sensor is set to zero, or the wheel is one rotation out instead.
So what you have is either a problem in the shifter buttons, the clock spring, or the wires/connectors for the clock spring and shifter buttons isntead.
If the shop did not pull the steering wheel, did not screw up the connectors under the dash, then bank that the problem was either the clock spring destroyed by the wheel turned a few winds disconnected, or they did someone in the tune that took out the shifter buttons isntead.
Bottom line, since don't have a clue what the shop did to your car/what they pulled apart or not, best advice I can give you, is take the car back to the shop that worked on it, and let them fix the problem on their own dime they created instead. Hell, problem could be just something they did in the tune that needs to be corrected on a reflash instead.

Sliding slightly off topic here,,,,, C6 AT 2005........... Horn pushed from the steering wheel > nothing. The horn does beep when leaving the FOB in the car and closing the door and when locking the car with the FOB.
Any ideas appreciated, thanks.
