Also looking into this too. I will revive this forum to shed more light on the problem.
There is basically no answers online from anyone. Im 99% positive no one has actually taken a column shift 3.5TT PI and made it shift manually like god intended.
From what I have gathered through manuals and from some professionals, if you have a column shifter… the PCM doesn’t have coding to shift the transmission. Im looking into possibly swapping my PCM for one out of an SHO (If your car is a 3.5TT). Or option 2, attempt to force write it through HPtuners.
Just bought another daily so I'm going to try this soon. Only other option I can think is take it to someone who can write PCMs.
For the wheel/shifters. Simple bolt up. Bought a wheel for my 14’ from a 14’ SHO on ebay. $150. Great shape. 15 minute swap. All buttons work exactly the same. (minus where it has paddle shifters on the back)
You should already have wires on the column going through the clockspring.
According to factory wiring manual and my own two eyes…The other thing you’ll notice is no wires to the PCM itself after the column.
I have reached out to a couple online tuning companies to see what input they may have about the PCM programming and will update this forum.
I know theres guys out there… future and present…who will want to do this as these cars become more available coming out of service.
If anyone has any more information on this topic please let me know.
