Sorry it has taken me so long to reply, I got called away for a trip to Colorado. But thank you for your help.
After scrolling further through the thread describing how to read the handshake method I found out that you are right. The code was two longs and four shorts: duty C solenoid.
I did some slow tight circle testing in a parking lot, but still was not able to detect any binding.
Next I pulled and reinstalled the fuse for the tcu, which cleared the Power code and then did a short drive resulting in another fault on the duty c solenoid.
What else might I check?
