5R55E Trans - RPM's constant, speed increasing

[PODHokie]

I have a 1999 Sport and when I'm accelerating (like on an on-ramp or something) I noticed the engine speed will stay constant at about 3000RPM, while the vehicle speed increases until it reaches a shift point and then it shifts fine. I can feel it going through the gears, but under acceleration it does this. Should I be worried? It kind of sounds like the inverse of a slipping transmission - where revs go up without a change in vehicle speed.

Thoughts?

I am certainly no expert, but I believe that is how a torque converter functions before the clutch goes into lock-up. Not really sure though, but posting up to expand the conversation.
