My truck has a 700R4, 3.73 gears and 29" tires. My tach reads a little under 1900RPM when I'm going 60 MPH.

If your overdrive and torque converter clutch are working correctly and you have a vacuum switch in the torque converter clutch wiring, your transmission should feel more like a 5 speed automatic. It will shift like this: first-second-third-overdrive-tcc.
