5speed ford ranger problem is shifting

Sounds like your clutch is not releasing enough to allow you to engage or disengage. It is dragging which causes hard engagement and disengagement. Possible causes are, Low fluid in the master cylinder to the clutch, or bad slave cylinder down by the bell housing, or badly worn pressure plate, or air in the line leading to the slave cylinder. You will need to eliminate these items one by one by testing to find the bad item in the system. Good luck
