Rpms rev but will not shift from 2nd to 3rd gear
Sounds like an electronic pressure switch or electronic governor. Your engine check light should be on or intermittent and it should have a code. A lot of parts stores or transmission repair shop should be able to tell you with a code reader.

its possible that your intake manifold is leaking down onto the spark plugs causing the problem to check pull a spark plug out and see if the tip is covered in oil
SOURCE: wont shift into 2nd gear revs high until it finally goes into 3rd
If there is a Auto Zone around your area, have the blazer scanned for any DTC codes that is related to the transmission issues. It could be a fault sensor, bad wires, or bad solenoid in the valve body. The scan should help indicate if there is an electrical issues or it's going to be mechanical. You can try adding a transmission additive to flush out the system and then replace the transmission filter and oil. Make sure you flush out all the transmission oil, it could be as simple as the 2nd and 4th solenoids are seized with dirt and not activating. Good luck and keep me posted. The solenoid is in the valve body and is not that expansive for the parts, you just have to find a good transmission shop that will fix this simple problem and not try to get you to put in a new transmission.

Drop the pan, odds are the shift solenoid is out, its located at the front of the trans on the driver side. I'm sure your check engine light is on that will comment about the timing/shift solenoid being bad. I had the same problem with mine. The solenoid had plastic coming out of the inside. To remove it you'll find a small C clip holding it in, just take a small screw driver and pull the clip out. The part cost me like $36 from my local dealership. And its a longer solenoid. I believe its the 3-2 downshift solenoid. I do have the part number if you need it.
