Does your torque converted (lockup) act like this on the highway?

Default Does your torque converter (lockup) act like this on the highway?

Just wondering because it seems strange to me.

On previous cars I've owned, once I reach a certain speed (anywhere from 45 to 60MPH) and reach a steady cruising throttle position, the torque converter will 'lock up'. What this means to the driver is basically that the RPMs stay consistant with their speed. It's intended to give better gas milage and a more 'linear/direct' feeling when cruising.

But what I've noticed wth mg GS400 is that I can't ever tell that the torque converter has actually locked up... matter of fact I'm pretty sure it's not... either that or it's very sensetive. The reason I say this is that if I'm cruising at 60MPH on flat terrain my RPM is pretty much right at 2000. But if I let off the gas, the RPMs drop sharply to something like 1600-1700 RPM before the car even starts decelerating. Then if I start cruising again they go back up to 2000 RPM.

This is not something that most cars I've owned in the past have done... in that situation they would just maintain their cruising RPM even if I let off the gas, until they started to slow down.

Is this normal or is my torque converter acting strangely?
