I had my wife's 190E 1991 2.6 the last few days. I noticed that on the freeway the tach reads 3200 rpm at 65 mph. That seemed quite high. It goes through all four gears but there doesn't seem to be an overdrive. I researched a bit on the internet and found a "review" of her car that did not list an overdrive. My Mits. Diamante is 2400 at 65 mph so I doubt that her car was designed to rev that high while just cruising. Any thought? (Tires are correct size).
Thanks in advance,
