Wow, so far from searching the forum I've come up with people having simular problems that claimed it was caused/cured by:
Fuel pump going out
Coolant temp sensor
Dirty trans fluid
Bad torque convertor, cured by bottle of additive
Transmission on it's last leg (slipping)
Bad wiring connection
Broken wire to trans
Worn/grounded wire to trans
Bad computer program
And probably some other's that I can't even remember.
So far I'm thinking brake switch. This morning it performed perfectly fine, and I tested touching the brake to see if the TCC disengages. It did, but I barely put any pressure on the brake, and swear it didn't even move. If the adjustment is that close I could see it sometimes being "over the edge" and the truck thinking the brake is starting to be pushed.
