TRANSMISSION WILL NOT SHIFT INTO OVERDRIVE

2001 Oldsmobile Aurora • 159,000 miles

The transmission in my Aurora smoothly shifts from 1st to 2nd and 2nd to 3rd, but never makes the shift into fourth (overdrive). Even though the tachometer reads 3,000 rpm @ 70mph, the transmission does not slip. I can hear a faint "whine" while driving at 55mph. Any ideas on what could be causing this condition and how I can repair it?

Have a trans guy scan for codes but it may be a torque converter clutch or the overdrive clutch is shot
