You never imagine that it could happen to you, and then... 
Halfway through the cooldown lap of my last session of the day today at an HPDE event, my car went into limp mode, and only gears 2, 4, and 6 were available. MFD said "T/M failure, visit dealer." I was able to limp back to the paddock, park, and let the car cool down. After 30 minutes, it started up without problems, and both clutches worked, but a few miles from the track on my way home I got the same message, plus a check engine light and an "Engine system failure, visit dealer" message in addition to the T/M failure message.
I am typing this from a hotel room, where I will spend the night before a flatbed comes to pick up the car tomorrow morning, and drop us off at my dealer near my home 100 miles away.
I have no powertrain mods, nor do I have a Cobb AP (so I can't get exact codes just yet). I've been running Willall WR35TM since the car had 9K miles, changed again at 18K miles. The car is a daily driver, just passed 25K miles, and I was going to change the trans oil again at 27K.
Unlike my last track day, where the ambient temps were in the low 100s, this time the weather was much nicer, and ambient temps never got above 90F. I drove the car hard, but not excessively so, and none of my MFD temp gauges (coolant, trans oil, engine oil) ever went into the red.
After the car cooled down and I started it up again, it sounded and functioned fine, i.e. it was shifting smoothly in Auto mode from 1 through 6 as I was driving away from the track. I also had the "torque split" gauge visible on the MFD, and the AWD system seemed to work fine. I am no expert, but I think this means this likely isn't a circlip failure, nor is it a completely jammed/mechanically busted transmission. That leaves the infamous solenoid malfunction issue.
Any ideas, especially from those who have experienced transmission problems? Thanks in advance.
(Too bad, it was an awesome track day...)
Edit: My car is a 2010, but one of the very early 2010s (built in January 2009, I think). Also, my symptoms sound exactly like those described by another member in this thread: http://www.nagtroc.org/forums/index.php?/topic/58883-tranny-went-to-failsafe-at-track-had-to-flatbed-it-home/
