Try this test to see if your Torque Converter Clutch is engaging and disengaging. When at a steady cruise around 60-70, in 5th gear. With your foot steady on the gas pedal, Lightly tap the brake pedal to see your RPMS increase by maybe 200-300rpm, this is normal because the TCC will actually apply help decrease rpms when driving at a moderate highway speed with no abrupt acceleration or deceleration. DO NOT apply the brakes so hard it will cause the vehicle to deccelerate.

well of course i didnt expect 'free speed', i noticed this since cat back exhaust installed few months ago. sorry, i'm pretty new w/ car stuff....so my question might sounds 'stupid' for some people

I just had my 04 GS300 at 100 mph this morning, rpm was 4000, I'll try 80 tomorrow morning, will let you know, wonder what my rpm will be at 140? lol

OK, this morning tried 80mph and rpms sat at 3175, 04 GS300.

i couldn't even hit 80 on the drive home the last few days, but i did manage to hit 80 on the way to work this morning and my 99gs400 w/ 20's (someone said that the tire size will affect the rpm's) (I wonder if this will recalculate somehow in smarter cars???) and at 80 mph my rpm's were at like 2.7.

does anyone know what the optimal mpg rpm would be in top gear set on cruise? i have always wondered if at 75 mph at 2.45 rpm is actually that much better than say 80 mph at 2.7 rpm??

Any increase in speed is going to cost you in terms of MPG. As the car increases in speed the drag increases exponential. Better off driving the speed limit or less if your worried about MPG.
