i believe that my tc is coming out when im cruising in over drive. anywhere from 55 and higher. i was curious if i switched my tc lockup switch to on if that would stop it from doing that when cruising? im wanting to take about a 500 mile trip and not sure if that would stop it from unlocking when highway driving!

 

It would determine if it is electrical interference or not.
