Could anybody answer me this, could a screwy torque converter cause shift points to be effected?

I don't think its just a shift point problem (which i'm told is the TV link) because what about the whole RPM thing? when you let off the gas, engine RPMS go to idle. Its like the engine rev's aren't syncin with the tranny revs until throttle is applied. Again, i know nothing about auto trannys, but this sounds like torq converter. anyone agree?

BTW, the tranny does hit all 3 gears. 2nd kicks in at 4500rpm, and 3rd at 5000rpm. I drove the car on the interstate for about 70 miles yesterday to get back from work. And other than some odd driving style on my part to keep the engine at speed and low rpms, everything went fine.
