SOURCE: 4000 rpm at 70 miles per hour

You should have another gear "5th" at 70mph your tacho should read about 2500 rpm.
Make sure you don't need to depress something or push the gear stick against a spring to select 5th.
Is there a gear layout on top of the gearstick knob, do you have 5th gear on there?
The highest gear ratio is a little over 1 to 1 so at 70 mph you would expect 3500 rpm, but, it is a little over 1 to 1 so it will be closer to 2500rpm.

SOURCE: Blazer transmission not shifting properly beetween 1 and 2

Your going to have to get the ECM scanned, Auto Zone scan's for free and most garage now will scan for $10.00 to $15.00 since they all have the scanners now and need the business.
You could have a Vehicle Velocity Sensor (V V S)  going bad or the wire harness it self. The V.V.S tells the ECM how fast the drive shaft is rotating and calculate's what gear it should be in relative with the engine speed and throttle position, and transmission fluid pressure.
Regardless you need the Blazer scanned to pin point why your transmission is shifting the way it is. Could be as simple as time for transmission oil and filter change for $125.00 or a loose wire harness.
Check your transmission fluid and try not to run the blazer to hard, to replace the transmission start at $1,900.00 for a rebuilt.
Good luck and hope this helps. Keep me posted
