engine surge after lock up Almost every time my converter locks up in 4th my engine will surge. It only happens under light acceleration and to stop it I either let off the gas or give it more. I have a vacuum modulated 4L60E. Does anyone know what could cause this.

It only happens when the converter locks up around 50 mph. The engine rpms will go up and down about 200 rpms. It will stop if I give it more/less gas. So if I was to hit the brake it would have already stoped.
