I have been fighting this problem with torque converter lock/unlock for at long time. I did everything I could think of and all I could read online. Foil, rewire/ wire modifications, battery replace, clean grounds. Long story short, change out the brake light switch. The dealer hooked the truck up to a laptop and drove it while the truck was doing it's thing. The switch was shorting out sometimes and that was causing the transmission to unlock/ lock. I tell everyone to change this $20.00 switch first before jumping through all the hoops I did
