Default Bad Torque Converter???

I'm pretty sure my TC lock up is bad. when the engine is cold still, under acceleration and steady state, the car will pull and lag, as if the torque converter is locking and unlocking about once a second. This problem goes away when the engine is warmed up and also goes away when i put one foot on the brake(unlocking it) and drive. Has anyone had any experiences with bad sensors or bad TCs or anything?

In the transmission there is a Torque Converter Clutch and a soleniod to go with that. It sounds like the soleniod may be a possibliltiy if your theory is correct. I believe a soleniod can be changed fairly easily at a shop.

If the TCC solonoid is having issues, or there'* too much slip in lockup, you should have a code and a check engine light.
