When is does this, does your O/D light blink on/off? What rpm and speed range do the symptoms occur in? Is it at the point where the T/C begins to lock, or before that?
It could really be a variety of things. Hard to tell until more information is given. My gut is telling me low line pressure due to valve body or pump issues.

On edit: Do you have a trans temp guage?

Third brake light is wired into the same circuit that controls torque convertor lock/unlock. If the bulb is burnt, the circuit is broken and the t.c. will not lockup.
Doesn't sound like the issue the o.p. is having, but it's worth a shot.
