You may be confusing torque converter lockup for high gear. When the torque converter locks up, it can feel like another gear since the rpms drop significantly. One way to tell if you have torque converter lockup is by tickling the accelerator in gear and see if the tachometer responds. In lockup it won't respond much at all.

Most models don't allow the torque converter to lock up until the coolant is warm, e.g., after a few miles.
