T/C Lock Light - How to unlock?

[cg25713]

How do I unlock the T/C so my T/C light will go out?

When I received my M1123, it had the stuck T/C lock light. I took it to a nearby gravel parking lot and drove in a tight figure 8 once forward, and once backward. About half way through the backward run, it popped loose and I was able to shift it in and out of all ranges.

Drive in reverse for about 20ft, this is common.
