Could this be a tcc solenoid or converter problem? I just recently started having this problem to where I can cruise on the highway at about 60-65 (Yes, I usually drive the speedlimit 
) and it feels like the converter unlocks. I had a local guy scan it to see what was up, well going down the road it locked up fine then after a mile or so it has this unlock feeling but on EFI live it shows to still be locked 
could this be a solenoid or maybe the converter clutches are slipping? No codes are being shown.

I would try maxing out the missfire tables. Unless the codes disabled if the PCM comands lockup and it does not happen you should get a po1870 code

The codes have not been disabled and I have no P1870 code showing.
If it's a solenoid wouldn't that be showing some kind of code though? I'm starting to think it's the converter clutches slipping.
I'm clueless
Use a scan tool and see if you can hear the solenoid click on and off (obviously with the car off in a quiet area). If you can hear it click, take it out for a drive. When you think it unlocks, use the scanner to increase the line pressure and see if that helps.
