I'm currently having issues with my TC, around 40mph and 70/75 it kicks in and out. I have to floor it or hit the brake for it to go away. Has any one had this similiar issue?

Do you have the TCC connected to the brake switch correctly? If so, you probably need to get your "tuner" to adjust the settings in the tune.
