Range 1: 7300-7500 RPM Range 2: 7500-7700 RPM Range 3: 7700-7900 RPM Range 4: 7900-8400 RPM Range 5: 8400-9500 RPM Range 6: 9500-11000 RPM Ranges 1 - 3 are not considered problematic and they are very common. You can get these in normal driving by running your car up to the red line before shifting. Ranges 4 - 6 are typically caused by something like missing a shift. An example might be trying to downshift to 4th gear and accidentally hitting second gear. Over revs in Range 4 are right on the line - sometimes a problem and sometimes not. Over revs in Range 5 - 6 are much more likely to cause engine damage.
