Default TH350C Testing

This is my first automatic automobile. How do I test in order to find out if the lock-up system is working correctly in my Corvette? Thanks!

At 45-50 MPH the TCC "should" be locked up. Maintain a steady light pressure on the throttle and touch the brake just enough the brake lights come on. You should feel the slight bump when the TCC unlocks and see the RPM slightly increase.

Make sure you are aware of traffic around you when to touch the brake-

So, lift foot off gas and touch brake pedal or leave foot on gas and touch brake with other foot?

Okay.I had a day to test it. I did not see any change. I can feel the lockup go in. It feels like a fourth shift. When driving the car, how do you know when it disengages on its own? I am just wondering if it's related to my surging issue between 40 and 50 MPH.
