4 speed + overdrive is stock, rangers never came with 6 forward speeds
If you are at 3,000 RPM at 70 MPH then you have a 4.56 ratio rear axle which is used for Towing at lower speeds not highway speed driving.
If you switched to a 3.73 ratio you would be at 2,450rpm at 70MPH
3.73 is OK for towing and commuting
3.55 ratio would be 2,300rpm at 70MPH
