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 the same problem?
